6-Methyl-[1,2,4]triazolo[1,5-b][1,2,4]triazine CAS 61139-75-1 chemical structure

Description

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.

6-Methyl-[1,2,4]triazolo[1,5-b][1,2,4]triazine (CAS 61139-75-1) is a high-purity analytical reference standard with the molecular formula C5H5N5 and a molecular weight of 135.13 g/mol.

6-Methyl-[1,2,4]triazolo[1,5-b][1,2,4]triazine (C5H5N5) contains a nitrile group. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
