Chemical Structure

1,2-Dimethyl-1H-1,2,3-triazole-5(2H)-thione CAS 64808-28-2 chemical structure

Description

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.

CATO supplies 1,2-Dimethyl-1H-1,2,3-triazole-5(2H)-thione (CAS 64808-28-2), a certified reference material (molecular formula C4H7N3S, MW 129.18 g/mol) for analytical method development and quality control.

Structurally, 1,2-Dimethyl-1H-1,2,3-triazole-5(2H)-thione (C4H7N3S) contains a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 129.18 g/mol, it falls into the low-molecular-weight range. 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.
