Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(4-(2,4-dichlorophenyl)thiazol-2-yl)-2-((3-(trifluoromethyl)phenyl)thio)acetamide.
N-(4-(2,4-dichlorophenyl)thiazol-2-yl)-2-((3-(trifluoromethyl)phenyl)thio)acetamide (CAS 338957-97-4), molecular formula C18H11Cl2F3N2OS2 and molecular weight 463.32 g/mol, is a CATO reference standard with documented purity and traceability.
N-(4-(2,4-dichlorophenyl)thiazol-2-yl)-2-((3-(trifluoromethyl)phenyl)thio)acetamide (C18H11Cl2F3N2OS2) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
