Chemical Structure

5-Chloro-2,3-difluoro-4-methylbenzoyl chloride CAS 914635-55-5 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 5-Chloro-2,3-difluoro-4-methylbenzoyl chloride.

CATO supplies 5-Chloro-2,3-difluoro-4-methylbenzoyl chloride (CAS 914635-55-5), a certified reference material (molecular formula C8H4Cl2F2O, MW 225.02 g/mol) for analytical method development and quality control.

The molecular framework of 5-Chloro-2,3-difluoro-4-methylbenzoyl chloride (C8H4Cl2F2O) is characterized by a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

CATO manufactures 5-Chloro-2,3-difluoro-4-methylbenzoyl chloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
