3-Chloro-4-hydroxybenzenesulfonamide CAS 25319-97-5

Description

The occurrence of 3-Chloro-4-hydroxybenzenesulfonamide is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-Chloro-4-hydroxybenzenesulfonamide (CAS 25319-97-5), a certified reference material (molecular formula C6H6ClNO3S, MW 207.63 g/mol) for analytical method development and quality control.

The molecular framework of 3-Chloro-4-hydroxybenzenesulfonamide (C6H6ClNO3S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures 3-Chloro-4-hydroxybenzenesulfonamide 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.
