Chemical Structure

(2-Cyano-4,5-difluorophenyl)boronic acid CAS 2199440-55-4 chemical structure

Description

(2-Cyano-4,5-difluorophenyl)boronic acid (CAS 2199440-55-4) is a high-purity analytical reference standard with the molecular formula C7H4BF2NO2 and a molecular weight of 182.92 g/mol.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, (2-Cyano-4,5-difluorophenyl)boronic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 182.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), (2-Cyano-4,5-difluorophenyl)boronic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
