Chemical Structure

2-Phenyl-2H-benzo[d][1,2,3]triazole CAS 1916-72-9 chemical structure

Description

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.

2-Phenyl-2H-benzo[d][1,2,3]triazole (CAS 1916-72-9), molecular formula C12H9N3 and molecular weight 195.22 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Phenyl-2H-benzo[d][1,2,3]triazole (C12H9N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), 2-Phenyl-2H-benzo[d][1,2,3]triazole 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.
