Description
CATO manufactures Methyl 1,5-diphenyl-1,2,4-triazole-3-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
Methyl 1,5-diphenyl-1,2,4-triazole-3-carboxylate (CAS 89060-64-0), molecular formula C16H13N3O2 and molecular weight 279.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl 1,5-diphenyl-1,2,4-triazole-3-carboxylate (C16H13N3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
