Chemical Structure

1H-1,2,4-Triazol-5(4H)-one CAS 122333-30-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 85.06 g/mol gives 1H-1,2,4-Triazol-5(4H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1H-1,2,4-Triazol-5(4H)-one (CAS 122333-30-6), a certified reference material (molecular formula C2H3N3O, MW 85.06 g/mol) for analytical method development and quality control.

The molecular framework of 1H-1,2,4-Triazol-5(4H)-one (C2H3N3O) is characterized by an amide group, a hydroxyl group, an ether linkage. 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.

CATO manufactures 1H-1,2,4-Triazol-5(4H)-one 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.
