Chemical Structure

1 H-1,2,4-Triazole CAS 288-88-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 69.07 g/mol gives 1 H-1,2,4-Triazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1 H-1,2,4-Triazole (CAS 288-88-0), a certified reference material (molecular formula C2H3N3, MW 69.07 g/mol) for analytical method development and quality control.

The molecular framework of 1 H-1,2,4-Triazole (C2H3N3) 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.
