N-(2,4-Dichlorophenyl)-1-(2,5-dichlorophenyl)-5-methyl-1H-1,2,4-triazole-3-carboxamide CAS 338398-31-5

Description

Compared with other compounds in its class, the molecular weight of 416.09 g/mol gives N-(2,4-Dichlorophenyl)-1-(2,5-dichlorophenyl)-5-methyl-1H-1,2,4-triazole-3-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-(2,4-Dichlorophenyl)-1-(2,5-dichlorophenyl)-5-methyl-1H-1,2,4-triazole-3-carboxamide (CAS 338398-31-5), molecular formula C16H10Cl4N4O and molecular weight 416.09 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-(2,4-Dichlorophenyl)-1-(2,5-dichlorophenyl)-5-methyl-1H-1,2,4-triazole-3-carboxamide (C16H10Cl4N4O) is characterized by a nitrogen-containing heterocyclic scaffold, 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. 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.
