3-Fluoro-2-methylbenzeneboronic acid, CAS 163517-61-1, is an aryl boronic acid used primarily as a synthetic building block in research and chemical manufacturing. Its structure contains a boronic acid group, one fluorine substituent, and one methyl substituent on an aromatic ring. Based on its molecular composition, its molecular formula is commonly represented as C7H8BFO2, with a calculated molecular weight of approximately 153.95 g/mol. At Maison Chemical, we support buyers with product identification, specification review, documentation, packaging coordination, and export-oriented supply communication.
3-Fluoro-2-methylbenzeneboronic acid belongs to the family of organic boronic acids and, more specifically, substituted aryl boronic acids. The boronic acid functionality can participate in palladium-catalyzed Suzuki–Miyaura coupling reactions with suitable aryl or vinyl electrophiles. The fluoro and methyl substituents remain part of the resulting aromatic structure and can influence molecular polarity, steric environment, and downstream structure–activity studies.
The CAS number 163517-61-1 is the primary registry identifier used to distinguish this compound from other fluorinated or methyl-substituted benzeneboronic acids. Buyers should confirm the CAS number, chemical name, molecular formula, molecular weight, and structure before placing an order. This verification is especially important because positional isomers can have similar names while offering different reactivity and application results.
The principal role of this compound is to provide an aryl fragment during carbon–carbon bond-forming synthesis. In a suitable Suzuki coupling, the boronic acid group reacts with an appropriate halide or related electrophile to construct a biaryl, aryl–heteroaryl, or substituted alkene framework. Actual conversion depends on the reaction partner, catalyst system, base, solvent, temperature, reaction time, and work-up procedure.
The fluorine atom provides a defined substituent for medicinal chemistry, agrochemical research, and advanced organic synthesis programs. The methyl group can alter steric behavior and electronic properties relative to an unsubstituted fluorophenyl boronic acid. Because these effects are application-dependent, I recommend evaluating the compound within the complete target molecule rather than treating the substituents as independent performance guarantees.
These are synthetic-use categories rather than claims that the compound is an active pharmaceutical ingredient, pesticide, or finished product. Its suitability must be confirmed through the buyer’s own reaction screening, analytical testing, and regulatory review. We therefore avoid presenting a single reaction condition as universally applicable.
Commercial aryl boronic acids may be supplied in different quality grades, package sizes, and documentation formats. The same CAS number can be requested for research use, route scouting, process development, or larger-scale manufacturing support, but the documentation expectations may differ between these use cases. Buyers should distinguish between a standard catalog supply, a project-specific batch, and a custom or scale-up requirement.
Some boronic acids may also show differences in physical form, such as powder, crystalline solid, or another solid presentation. The appearance alone is not sufficient to confirm identity or quality. A current certificate of analysis, analytical data, and safety documentation should be used for release decisions.

| Specification item | Why it matters |
|---|---|
| CAS number | Confirms that the requested material is CAS 163517-61-1 rather than a positional isomer. |
| Chemical name and structure | Verifies the 3-fluoro and 2-methyl substitution pattern. |
| Molecular formula | Commonly identified as C7H8BFO2; buyers should confirm against the supplier’s documentation. |
| Molecular weight | Approximately 153.95 g/mol based on the stated formula. |
| Purity | Should be agreed according to the intended reaction, analytical method, and project stage. |
| Analytical package | May include HPLC, GC, NMR, water, residual solvent, or other data where applicable. |
| Packaging and storage | Should follow the applicable product specification and safety data sheet. |
Purity should not be assumed from the chemical name or CAS number alone. For a buyer comparing suppliers, the relevant question is whether the offered batch meets the agreed specification by a stated analytical method. For example, a customer may request a purity specification expressed as a percentage, but the acceptance limit, test method, and reporting basis should be confirmed in writing before procurement.
For early discovery work, buyers may prioritize availability, small packaging, and rapid technical confirmation. For process development, the focus usually shifts toward batch consistency, impurity profiles, reproducible documentation, and supply continuity. For commercial planning, buyers should additionally review production capacity, lead-time assumptions, packaging configuration, transport requirements, and change-notification practices.
I recommend requesting a current certificate of analysis, safety data sheet, product specification, and representative analytical information before purchase. The documentation should clearly identify the product as 3-Fluoro-2-methylbenzeneboronic acid CAS 163517-61-1. If the material will enter a regulated development process, the buyer should also define any additional documentation requirements at the quotation stage.
Organic boronic acids should be handled according to the supplier’s SDS and the buyer’s laboratory or manufacturing procedures. Buyers should not infer storage temperature, shelf life, or stability from the product name alone because these details can depend on packaging, environmental exposure, and the specific batch. Maison Chemical can review the requested handling and documentation requirements before shipment so that the supply arrangement is aligned with the customer’s process.
Maison Chemical supplies 3-Fluoro-2-methylbenzeneboronic acid CAS 163517-61-1 for customers evaluating organic synthesis intermediates and aryl boronic acid building blocks. Our role is to help customers confirm chemical identity, review available specifications, coordinate packaging, and clarify commercial requirements. We can also discuss whether a request is intended for laboratory research, route development, or a larger purchasing program.
When a buyer sends an inquiry, the most useful information includes the required quantity, target purity, destination country, intended application, preferred packaging, and requested delivery schedule. These details allow us to prepare a more relevant quotation instead of giving a generic product response. Where a requirement is not confirmed, we use conservative wording and recommend technical approval against the final batch documentation.
3-Fluoro-2-methylbenzeneboronic acid CAS 163517-61-1 is a defined aromatic boronic acid intermediate for synthetic programs that require its specific fluorine and methyl substitution pattern. It may be appropriate for medicinal chemistry, agrochemical research, process development, and other applications involving aryl coupling, but suitability depends on the customer’s reaction design and quality requirements. The correct purchasing decision should therefore combine structural confirmation with batch-specific analytical review.
As the next step, send Maison Chemical your required quantity, purity target, packaging preference, destination, and delivery expectations. We can then confirm available supply information, documentation, and commercial options for your project.
