5-Bromo-2,3-difluoro-4-methylphenylboronic acid CAS 2121513-00-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Bromo-2,3-difluoro-4-methylphenylboronic acid.

CATO supplies 5-Bromo-2,3-difluoro-4-methylphenylboronic acid (CAS 2121513-00-4), a certified reference material (molecular formula C7H6BBrF2O2, MW 250.83 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, 5-Bromo-2,3-difluoro-4-methylphenylboronic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 250.83 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).

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), 5-Bromo-2,3-difluoro-4-methylphenylboronic 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.
