Chemical Structure

4-(1H-1,2,4-Triazol-1-yl)benzonitrile CAS 25699-89-2 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.

4-(1H-1,2,4-Triazol-1-yl)benzonitrile (CAS 25699-89-2), molecular formula C9H6N4 and molecular weight 170.17 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-(1H-1,2,4-Triazol-1-yl)benzonitrile (C9H6N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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).

As a certified reference material (CRM), 4-(1H-1,2,4-Triazol-1-yl)benzonitrile 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.
