Description
CATO manufactures Ethyl 2-acetamidobenzo[b]thiophene-3-carboxylate 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.
Ethyl 2-acetamidobenzo[b]thiophene-3-carboxylate (CAS 7311-77-5), molecular formula C13H13NO3S and molecular weight 263.31 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 2-acetamidobenzo[b]thiophene-3-carboxylate (C13H13NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
