3-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]sulfanyl}-5-[(E)-2-[(4-methoxyphenyl)amino]ethenyl]-1,2-thiazole-4-carbonitrile (CAS 338412-95-6), molecular formula C19H12ClF3N4OS2 and molecular weight 468.90 g/mol, is a CATO reference standard with documented purity and traceability.
3-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]sulfanyl}-5-[(E)-2-[(4-methoxyphenyl)amino]ethenyl]-1,2-thiazole-4-carbonitrile (C19H12ClF3N4OS2) 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; 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.
