Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Cyano-2-ethyl-3-nitrobenzenesulfonyl chloride.
CATO supplies 4-Cyano-2-ethyl-3-nitrobenzenesulfonyl chloride (CAS 1807292-37-0), a certified reference material (molecular formula C9H7ClN2O4S, MW 274.68 g/mol) for analytical method development and quality control.
4-Cyano-2-ethyl-3-nitrobenzenesulfonyl chloride (C9H7ClN2O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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. 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 4-Cyano-2-ethyl-3-nitrobenzenesulfonyl 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.
