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 Sodium (4-nitrophenyl)methanesulfonate.
Sodium (4-nitrophenyl)methanesulfonate (CAS 36639-50-6), molecular formula C7H6NO5SNa and molecular weight 239.18 g/mol, is a CATO reference standard with documented purity and traceability.
Sodium (4-nitrophenyl)methanesulfonate (C7H6NO5SNa) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 Sodium (4-nitrophenyl)methanesulfonate 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.
