3-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]sulfanyl}-5-[(2Z)-2-{[(4-methylphenyl)methoxy]imino}ethyl]-1,2-thiazole-4-carbonitrile (CAS 338413-10-8), molecular formula C20H14ClF3N4OS2 and molecular weight 482.93 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C20H14ClF3N4OS2, 3-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]sulfanyl}-5-[(2Z)-2-{[(4-methylphenyl)methoxy]imino}ethyl]-1,2-thiazole-4-carbonitrile contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 482.93 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
