N3,N3,1-Trimethyl-1H-1,2,4-triazole-3,5-diamine CAS 87009-70-9

Description

Compared with other compounds in its class, the molecular weight of 141.17 g/mol gives N3,N3,1-Trimethyl-1H-1,2,4-triazole-3,5-diamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N3,N3,1-Trimethyl-1H-1,2,4-triazole-3,5-diamine (CAS 87009-70-9) is a high-purity analytical reference standard with the molecular formula C5H11N5 and a molecular weight of 141.17 g/mol.

Owing to a nitrile group, N3,N3,1-Trimethyl-1H-1,2,4-triazole-3,5-diamine is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 141.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
