The occurrence of 6-Methyl-1,2,4-triazine-5(2H)-thione is closely related to a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 6-Methyl-1,2,4-triazine-5(2H)-thione (CAS 15969-18-3), a certified reference material (molecular formula C4H5N3S, MW 127.17 g/mol) for analytical method development and quality control.
The molecular framework of 6-Methyl-1,2,4-triazine-5(2H)-thione (C4H5N3S) is characterized by a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
