Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Chloro-4-methoxy-5-(trifluoromethyl)phenylboronic acid.
CATO supplies 3-Chloro-4-methoxy-5-(trifluoromethyl)phenylboronic acid (CAS 2121515-22-6), a certified reference material (molecular formula C8H7BClF3O3, MW 254.40 g/mol) for analytical method development and quality control.
Structurally, 3-Chloro-4-methoxy-5-(trifluoromethyl)phenylboronic acid (C8H7BClF3O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 254.40 g/mol, it falls into the medium-molecular-weight range. 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), 3-Chloro-4-methoxy-5-(trifluoromethyl)phenylboronic 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.
