CATO supplies 4,5-Diamino-2,4-dihydro-3H-1,2,4-triazole-3-thione (CAS 3529-50-8), a certified reference material (molecular formula C2H5N5S, MW 131.16 g/mol) for analytical method development and quality control.
The molecular framework of 4,5-Diamino-2,4-dihydro-3H-1,2,4-triazole-3-thione (C2H5N5S) 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.
