Description
CATO manufactures 5-Chloro-4-methylthiophene-2-sulfonamide 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.
CATO supplies 5-Chloro-4-methylthiophene-2-sulfonamide (CAS 1600331-21-2), a certified reference material (molecular formula C5H6ClNO2S2, MW 211.69 g/mol) for analytical method development and quality control.
The molecular framework of 5-Chloro-4-methylthiophene-2-sulfonamide (C5H6ClNO2S2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
