Chemical Structure

3,4-dimethyl-4H-1,2,4-triazole CAS 16778-74-8 chemical structure

Description

The molecular framework of 3,4-dimethyl-4H-1,2,4-triazole (C4H7N3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

3,4-dimethyl-4H-1,2,4-triazole (CAS 16778-74-8) is a high-purity analytical reference standard with the molecular formula C4H7N3 and a molecular weight of 97.12 g/mol.

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.
