Chemical Structure

5-Methyl-1-(propan-2-yl)-1h-pyrazole-4-sulfonyl chloride CAS 1006495-98-2 chemical structure

Description

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 supplies 5-Methyl-1-(propan-2-yl)-1h-pyrazole-4-sulfonyl chloride (CAS 1006495-98-2), a certified reference material (molecular formula C7H11ClN2O2S, MW 222.69 g/mol) for analytical method development and quality control.

The molecular framework of 5-Methyl-1-(propan-2-yl)-1h-pyrazole-4-sulfonyl chloride (C7H11ClN2O2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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.

CATO manufactures 5-Methyl-1-(propan-2-yl)-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.
