Chemical Structure
Description
The occurrence of 5-(3-Chlorophenyl)-N-(5,5-dimethyl-7-oxo-4,5,6,7-tetrahydrobenzo[d]thiazol-2-yl)isoxazole-3-carboxamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-(3-Chlorophenyl)-N-(5,5-dimethyl-7-oxo-4,5,6,7-tetrahydrobenzo[d]thiazol-2-yl)isoxazole-3-carboxamide (CAS 1388418-65-2) is a high-purity analytical reference standard with the molecular formula C19H16ClN3O3S and a molecular weight of 401.87 g/mol.
5-(3-Chlorophenyl)-N-(5,5-dimethyl-7-oxo-4,5,6,7-tetrahydrobenzo[d]thiazol-2-yl)isoxazole-3-carboxamide (C19H16ClN3O3S) contains a steroid 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.
