Chemical Structure

2-(3-methyl-1H-1,2,4-triazol-5-yl)acetonitrile CAS 86999-26-0 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-(3-methyl-1H-1,2,4-triazol-5-yl)acetonitrile (CAS 86999-26-0), molecular formula C5H6N4 and molecular weight 122.13 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(3-methyl-1H-1,2,4-triazol-5-yl)acetonitrile (C5H6N4) is characterized by 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 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).

CATO manufactures 2-(3-methyl-1H-1,2,4-triazol-5-yl)acetonitrile under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
