4-chloro-2,5-difluorobenzene-1-sulfonyl chloride CAS 286932-78-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-chloro-2,5-difluorobenzene-1-sulfonyl chloride.

CATO supplies 4-chloro-2,5-difluorobenzene-1-sulfonyl chloride (CAS 286932-78-3), a certified reference material (molecular formula C6H8Cl2F2O2S, MW 253.09 g/mol) for analytical method development and quality control.

The molecular framework of 4-chloro-2,5-difluorobenzene-1-sulfonyl chloride (C6H8Cl2F2O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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.

As a certified reference material (CRM), 4-chloro-2,5-difluorobenzene-1-sulfonyl chloride 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.
