Chemical Structure
Description
Owing to a nitrile group, 3-Methyl-1,4-dihydro-[1,2,4]triazolo[5,1-c][1,2,4]triazine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 137.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO supplies 3-Methyl-1,4-dihydro-[1,2,4]triazolo[5,1-c][1,2,4]triazine (CAS 61140-02-1), a certified reference material (molecular formula C5H7N5, MW 137.14 g/mol) for analytical method development and quality control.
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.
