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.
CATO supplies 2-Phenyl-6,7-dihydro-2H-benzo[d][1,2,3]triazol-4(5H)-one (CAS 97507-52-3), a certified reference material (molecular formula C12H11N3O, MW 213.24 g/mol) for analytical method development and quality control.
The molecular framework of 2-Phenyl-6,7-dihydro-2H-benzo[d][1,2,3]triazol-4(5H)-one (C12H11N3O) 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 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-6,7-dihydro-2H-benzo[d][1,2,3]triazol-4(5H)-one 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.
