3-(3,5-dimethyl-1H-pyrazol-1-yl)-5-methyl-4H-1,2,4-triazol-4-amine hydrochloride CAS 880-92-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(3,5-dimethyl-1H-pyrazol-1-yl)-5-methyl-4H-1,2,4-triazol-4-amine hydrochloride.

3-(3,5-dimethyl-1H-pyrazol-1-yl)-5-methyl-4H-1,2,4-triazol-4-amine hydrochloride (CAS 880-92-2), molecular formula C8H12N6HCl and molecular weight 228.68 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H12N6HCl, 3-(3,5-dimethyl-1H-pyrazol-1-yl)-5-methyl-4H-1,2,4-triazol-4-amine hydrochloride contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 228.68 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
