Chemical Structure

2-methylpyridine-3-sulfonyl chloride CAS 872001-95-1 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 2-methylpyridine-3-sulfonyl chloride.

CATO supplies 2-methylpyridine-3-sulfonyl chloride (CAS 872001-95-1), a certified reference material (molecular formula C6H12ClNO2S, MW 197.68 g/mol) for analytical method development and quality control.

2-methylpyridine-3-sulfonyl chloride (C6H12ClNO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
