Description
N-(3-chloro-2-methylphenyl)-1-(2,4-dichloro-5-methoxyphenyl)-5-methyl-1H-1,2,4-triazole-3-carboxamide (CAS 339015-12-2), molecular formula C18H15Cl3N4O2 and molecular weight 425.70 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(3-chloro-2-methylphenyl)-1-(2,4-dichloro-5-methoxyphenyl)-5-methyl-1H-1,2,4-triazole-3-carboxamide (C18H15Cl3N4O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
