5-Methyl-5,6,7,8-tetrahydro-[1,2,4]triazolo[4,3-a]pyrazine CAS 1823362-44-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Methyl-5,6,7,8-tetrahydro-[1,2,4]triazolo[4,3-a]pyrazine.

CATO supplies 5-Methyl-5,6,7,8-tetrahydro-[1,2,4]triazolo[4,3-a]pyrazine (CAS 1823362-44-2), a certified reference material (molecular formula C6H10N4, MW 138.17 g/mol) for analytical method development and quality control.

Based on its molecular formula C6H10N4, 5-Methyl-5,6,7,8-tetrahydro-[1,2,4]triazolo[4,3-a]pyrazine contains a nitrile group, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 138.17 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.
