Ethyl 4-amino-2-thioxo-3-(p-tolyl)-2,3-dihydrothiazole-5-carboxylate (CAS 57036-99-4), molecular formula C13H14N2O2S2 and molecular weight 294.39 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 4-amino-2-thioxo-3-(p-tolyl)-2,3-dihydrothiazole-5-carboxylate (C13H14N2O2S2) 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.
CATO manufactures Ethyl 4-amino-2-thioxo-3-(p-tolyl)-2,3-dihydrothiazole-5-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.
