Chemical Structure
Description
4-(3-Methyl-1H-1,2,4-triazol-5-yl)benzonitrile (CAS 1152889-67-2), molecular formula C10H8N4 and molecular weight 184.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(3-Methyl-1H-1,2,4-triazol-5-yl)benzonitrile (C10H8N4) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-(3-Methyl-1H-1,2,4-triazol-5-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.
