Chemical Structure
Description
CATO supplies 3-Ethyl-4-hydroxybenzenesulfonamide (CAS 207570-77-2), a certified reference material (molecular formula C8H11NO3S, MW 201.24 g/mol) for analytical method development and quality control.
3-Ethyl-4-hydroxybenzenesulfonamide (C8H11NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-Ethyl-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.
