Chemical Structure

1-vinyl-1,2,4-triaZole CAS 2764-83-2 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 1-vinyl-1,2,4-triaZole (CAS 2764-83-2), a certified reference material (molecular formula C4H5N3, MW 95.10 g/mol) for analytical method development and quality control.

The molecular framework of 1-vinyl-1,2,4-triaZole (C4H5N3) 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).

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.
