2-Bromopyridine-5-carbaldehyde, also known as 6-bromonicotinaldehyde, is a brominated pyridine aldehyde used as a building block in pharmaceutical, agrochemical, and research-chemical synthesis. Its key identity information is CAS 149806-06-4, molecular formula C6H4BrNO, and a calculated molecular weight of approximately 186.01 g/mol. As a B2B buyer, I recommend confirming identity, assay, impurity profile, packaging, shipping conditions, and documentation before comparing quotations. Maison Chemical can support product identification, quotation preparation, specification review, and export-oriented purchasing discussions subject to project and batch confirmation.

This guide is intended for pharmaceutical intermediate buyers, medicinal chemistry teams, contract development and manufacturing organizations, distributors, and procurement departments sourcing 2-Bromopyridine-5-carbaldehyde in commercial or development quantities. It is also useful for companies qualifying an additional supplier rather than relying on a single source. The purchasing priorities may differ between a laboratory trial and a regulated manufacturing program, so the requested specification should match the intended use.
For early-stage research, buyers may focus on availability, small-pack supply, analytical data, and rapid technical communication. For process development or manufacturing, buyers generally need stronger control of batch consistency, traceability, packaging, export documents, and change notification expectations. I recommend defining these requirements before requesting a final price because a lower unit price may not represent the lowest total procurement cost.
2-Bromopyridine-5-carbaldehyde contains both a brominated pyridine ring and an aldehyde functional group. These functional groups make it a useful intermediate for further chemical transformations, including carbon–carbon bond formation, condensation reactions, and other route-specific derivatizations. The exact reaction suitability must be assessed by the buyer’s chemist because conditions, catalysts, solvents, and downstream impurities vary by synthetic route.

The molecular weight shown above is a calculated identity value and should not be treated as a batch purity result. I advise buyers to compare the supplier’s product name, CAS number, formula, molecular weight, and analytical documents together. If any of these fields conflict, the discrepancy should be resolved before a purchase order is released.
A practical purchase specification should state the required assay method, minimum assay level, appearance, identification tests, water or residual solvent expectations where relevant, and the impurity limits important to the downstream process. Buyers should also ask whether the reported assay is based on chromatographic area normalization, an external standard, or another method. This distinction matters when comparing certificates from different suppliers.
For a development project, I would normally request a current certificate of analysis, chromatographic data where available, and a representative sample for internal confirmation. For a regulated or scale-up project, the buyer may additionally require batch traceability, analytical method information, safety documentation, statement of origin, and packaging details. These documents should be agreed during supplier qualification rather than requested only after shipment.
Quantity should be discussed in stages, such as a laboratory sample, a pilot quantity, and a production quantity. For example, a buyer may request quotations for 1 kg and 5 kg separately to understand how packaging and scale affect the unit price. These quantities are enquiry examples, not a fixed Maison Chemical MOQ, because the available pack size and commercial terms depend on batch status and project requirements.
Packaging should protect the material from contamination, moisture, physical damage, and unsuitable handling during transport. The buyer should confirm the container type, inner and outer packaging, label information, net weight, gross weight, and whether the shipment requires special handling. Storage instructions should be taken from the supplier’s current product documentation rather than assumed from the chemical name alone.
Start by explaining whether the material is intended for route scouting, medicinal chemistry, process development, analytical work, or commercial manufacturing. This context helps the supplier recommend an appropriate documentation package and quote the correct quantity. It also prevents a buyer from comparing a research pack with a manufacturing-oriented batch as though they were equivalent products.
Ask for the CAS number, formula, molecular weight, specification sheet, and a batch-specific certificate of analysis. Where the product is critical to a synthesis, request relevant chromatographic or spectroscopic information and clarify which tests are routine versus performed only by request. I recommend checking that the lot number on the certificate matches the proposed shipment and that the stated test methods are understandable to your quality team.
You will get efficient and thoughtful service from Maison Chemical.
Price is only one part of sourcing risk. Buyers should ask whether the quoted material is in stock, made to order, or subject to production scheduling, and should request a realistic lead-time estimate in calendar days or business days. A useful RFQ can compare an immediate development quantity with a planned 1 kg or 5 kg order, while clearly separating sample availability from repeat-order availability.
Before placing an order, confirm the currency, Incoterm, payment terms, quotation validity, shipping route, export documentation, packaging, and responsibility for customs clearance. The buyer should also check whether the supplier can provide an SDS and other documents required by the destination market. Maison Chemical can review these requirements during an enquiry and organize the quotation around the buyer’s intended destination and quantity, subject to confirmation.
I also recommend requesting clarification on change control, complaint handling, and replacement or credit procedures before a long-term supply relationship begins. These questions do not imply that a problem will occur; they establish how both parties will communicate if a specification, shipment, or document issue arises. A supplier that provides clear answers is easier to manage during scale-up and repeat purchasing.
One common mistake is ordering solely by chemical name without confirming the CAS number and analytical requirements. Another is assuming that a product described as “high purity” automatically meets the buyer’s process-specific impurity limits. Buyers should avoid treating a catalogue description as a substitute for a current batch certificate and should not approve material until the internal quality process is complete.
A further mistake is requesting a price without stating quantity, destination, packaging, and required documents. This often produces quotations that appear comparable but contain different commercial assumptions. I recommend sending a structured RFQ that includes the CAS number, target quantity, desired delivery window, destination country, documentation list, and any critical impurity or packaging requirements.
The final price of 2-Bromopyridine-5-carbaldehyde can vary with order quantity, batch availability, packaging, analytical requirements, shipping destination, and payment terms. A sample or small development pack may have a higher price per gram because testing, handling, and logistics are distributed over less material. Conversely, a larger order may improve the unit price but create additional inventory and shelf-life planning responsibilities for the buyer.
Lead time should be divided into material preparation, quality release, documentation, and transportation. I suggest asking the supplier to state these elements separately when timing is important, rather than accepting a single unsupported delivery promise. Maison Chemical can help buyers structure an enquiry around quantity, destination, required documentation, and target schedule so that the quotation is easier to evaluate.
Maison Chemical approaches this product as a B2B sourcing requirement rather than a simple catalogue transaction. We can help confirm the requested identity, review the buyer’s specification, prepare a quotation, discuss available quantities, and coordinate documentation requirements. The final availability, batch data, MOQ, price, and lead time should be confirmed for each enquiry because these items may change with production and logistics conditions.
For an efficient quotation, send the product name and CAS 149806-06-4 together with your required quantity, application stage, destination country, preferred Incoterm, packaging preference, and document requirements. If your quality team has a controlled specification, sharing it at the beginning allows us to identify any gaps before commercial confirmation. This process is particularly useful when the material will be used in a pharmaceutical intermediate or process-development program.
The right way to purchase 2-Bromopyridine-5-carbaldehyde CAS 149806-06-4 is to verify the chemical identity first, define the quality and documentation package second, and compare suppliers using the same commercial assumptions. A reliable decision should consider analytical evidence, supply continuity, packaging, logistics, and technical communication—not price alone. This approach reduces avoidable qualification and delivery risk without making unsupported assumptions about any supplier.
To begin, prepare an RFQ containing the CAS number, target quantity, destination, application stage, required assay and impurity information, packaging preference, and desired delivery window. Send these details to Maison Chemical for a product review and quotation discussion. We will then confirm the applicable specification, commercial terms, availability, and documentation for your project.
