Chemical Structure

3-(1h-1,2,4-Triazol-1-yl)propanenitrile CAS 76686-83-4 chemical structure

Description

3-(1h-1,2,4-Triazol-1-yl)propanenitrile (CAS 76686-83-4) is a high-purity analytical reference standard with the molecular formula C5H6N4 and a molecular weight of 122.13 g/mol.

The molecular framework of 3-(1h-1,2,4-Triazol-1-yl)propanenitrile (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).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
