Diethyl 2-(((4-(4-chlorophenyl)thiazol-2-yl)amino)methylene)malonate (CAS 71638-84-1), molecular formula C17H17ClN2O4S and molecular weight 380.85 g/mol, is a CATO reference standard with documented purity and traceability.
Diethyl 2-(((4-(4-chlorophenyl)thiazol-2-yl)amino)methylene)malonate (C17H17ClN2O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
As a certified reference material (CRM), Diethyl 2-(((4-(4-chlorophenyl)thiazol-2-yl)amino)methylene)malonate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
