Description
CATO manufactures Sulfo-N-succinimidyl 4-maleimidobutyrate sodium salt 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.
Sulfo-N-succinimidyl 4-maleimidobutyrate sodium salt (CAS 185332-92-7), molecular formula C12H11N2O9SNa and molecular weight 382.28 g/mol, is a CATO reference standard with documented purity and traceability.
Sulfo-N-succinimidyl 4-maleimidobutyrate sodium salt (C12H11N2O9SNa) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
