2-[1-(3,4-Dichlorophenyl)-5-methyl-1H-1,2,3-triazole-4-carbonyl]-3-(4-methoxyphenyl)-5-(trifluoromethyl)pyridine (CAS 882748-03-0), molecular formula C23H15Cl2F3N4O2 and molecular weight 507.29 g/mol, is a CATO reference standard with documented purity and traceability.
2-[1-(3,4-Dichlorophenyl)-5-methyl-1H-1,2,3-triazole-4-carbonyl]-3-(4-methoxyphenyl)-5-(trifluoromethyl)pyridine (C23H15Cl2F3N4O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/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.
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.
