1-[(2-Chlorophenyl)methyl]-3'-[3-(trifluoromethyl)phenyl]-1,2-dihydrospiro[indole-3,2'-[1,3]thiazolidine]-2,4'-dione (CAS 338418-97-6) is a high-purity analytical reference standard with the molecular formula C24H16ClF3N2O2S and a molecular weight of 488.91 g/mol.
1-[(2-Chlorophenyl)methyl]-3'-[3-(trifluoromethyl)phenyl]-1,2-dihydrospiro[indole-3,2'-[1,3]thiazolidine]-2,4'-dione (C24H16ClF3N2O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 1-[(2-Chlorophenyl)methyl]-3'-[3-(trifluoromethyl)phenyl]-1,2-dihydrospiro[indole-3,2'-[1,3]thiazolidine]-2,4'-dione 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.
