Description
CATO manufactures Ethyl 2-Amino-5-chlorothiazole-4-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-Amino-5-chlorothiazole-4-carboxylate (CAS 136539-01-0), molecular formula C6H7ClN2O2S and molecular weight 206.65 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 2-Amino-5-chlorothiazole-4-carboxylate (C6H7ClN2O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
