Chemical Structure

4-(Difluoromethyl)-6-methoxy-3-methylpyridine-2-sulfonyl chloride CAS 1805439-10-4 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 4-(Difluoromethyl)-6-methoxy-3-methylpyridine-2-sulfonyl chloride.

CATO supplies 4-(Difluoromethyl)-6-methoxy-3-methylpyridine-2-sulfonyl chloride (CAS 1805439-10-4), a certified reference material (molecular formula C8H8ClF2NO3S, MW 271.67 g/mol) for analytical method development and quality control.

4-(Difluoromethyl)-6-methoxy-3-methylpyridine-2-sulfonyl chloride (C8H8ClF2NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 4-(Difluoromethyl)-6-methoxy-3-methylpyridine-2-sulfonyl 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.
