Chemical Structure
Description
2-(3-Phenyl-1H-1,2,4-triazol-5-yl)benzoic acid (CAS 60510-58-9) is a high-purity analytical reference standard with the molecular formula C15H11N3O2 and a molecular weight of 265.27 g/mol.
The molecular framework of 2-(3-Phenyl-1H-1,2,4-triazol-5-yl)benzoic acid (C15H11N3O2) 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.
As a certified reference material (CRM), 2-(3-Phenyl-1H-1,2,4-triazol-5-yl)benzoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
