Chemical Structure

(3-CYANO-2,4-DIFLUOROPHENYL)BORONIC ACID 2,4-DIFLUORO-3-CYANOPHENYLBORONIC ACID 871940-31-7 BC001248 BORONIC ACID, B-(3-CYANO-2,4-DIFLUOROPHENYL)- CAS 871940-31-7 chemical structure

Description

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, (3-CYANO-2,4-DIFLUOROPHENYL)BORONIC ACID 2,4-DIFLUORO-3-CYANOPHENYLBORONIC ACID 871940-31-7 BC001248 BORONIC ACID, B-(3-CYANO-2,4-DIFLUOROPHENYL)- 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).

(3-CYANO-2,4-DIFLUOROPHENYL)BORONIC ACID 2,4-DIFLUORO-3-CYANOPHENYLBORONIC ACID 871940-31-7 BC001248 BORONIC ACID, B-(3-CYANO-2,4-DIFLUOROPHENYL)- (CAS 871940-31-7), molecular formula C7H4BF2NO2 and molecular weight 182.92 g/mol, is a CATO reference standard with documented purity and traceability.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), (3-CYANO-2,4-DIFLUOROPHENYL)BORONIC ACID 2,4-DIFLUORO-3-CYANOPHENYLBORONIC ACID 871940-31-7 BC001248 BORONIC ACID, B-(3-CYANO-2,4-DIFLUOROPHENYL)- 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.
