1-(2,4-Dichloro-5-methoxyphenyl)-N-(2-methoxyphenyl)-5-methyl-1H-1,2,4-triazole-3-carboxamide (CAS 339015-13-3), molecular formula C18H16Cl2N4O3 and molecular weight 407.25 g/mol, is a CATO reference standard with documented purity and traceability.
1-(2,4-Dichloro-5-methoxyphenyl)-N-(2-methoxyphenyl)-5-methyl-1H-1,2,4-triazole-3-carboxamide (C18H16Cl2N4O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
