Chemical Structure

N5,N5,1-trimethyl-1H-1,2,4-triazole-3,5-diamine CAS 26668-70-2 chemical structure

Description

N5,N5,1-trimethyl-1H-1,2,4-triazole-3,5-diamine (CAS 26668-70-2) is a high-purity analytical reference standard with the molecular formula C5H11N5 and a molecular weight of 141.17 g/mol.

Structurally, N5,N5,1-trimethyl-1H-1,2,4-triazole-3,5-diamine (C5H11N5) contains a nitrile group. 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 141.17 g/mol, it falls into the low-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
