1-(2,2-Difluoroethyl)-3-methyl-1h-pyrazole-4-sulfonyl chloride CAS 1006462-96-9 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 1-(2,2-Difluoroethyl)-3-methyl-1h-pyrazole-4-sulfonyl chloride.

CATO supplies 1-(2,2-Difluoroethyl)-3-methyl-1h-pyrazole-4-sulfonyl chloride (CAS 1006462-96-9), a certified reference material (molecular formula C6H7ClF2N2O2S, MW 244.65 g/mol) for analytical method development and quality control.

1-(2,2-Difluoroethyl)-3-methyl-1h-pyrazole-4-sulfonyl chloride (C6H7ClF2N2O2S) contains an amide group, a sulfone group, a carboxylic acid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 1-(2,2-Difluoroethyl)-3-methyl-1h-pyrazole-4-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.
