Chemical Structure
Description
CATO supplies 5-methyl-4-(methylsulfanyl)pyrrolo[2,1-f][1,2,4]triazine (CAS 859205-88-2), a certified reference material (molecular formula C8H17N3S, MW 187.31 g/mol) for analytical method development and quality control.
Based on its molecular formula C8H17N3S, 5-methyl-4-(methylsulfanyl)pyrrolo[2,1-f][1,2,4]triazine contains a nitrile group, sulfur-containing functionality; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 187.31 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.
