Chemical Structure

2-((4-Amino-4H-1,2,4-triazol-3-yl)thio)acetonitrile CAS 74599-36-3 chemical structure

Description

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.

CATO supplies 2-((4-Amino-4H-1,2,4-triazol-3-yl)thio)acetonitrile (CAS 74599-36-3), a certified reference material (molecular formula C4H5N5S, MW 155.18 g/mol) for analytical method development and quality control.

The molecular framework of 2-((4-Amino-4H-1,2,4-triazol-3-yl)thio)acetonitrile (C4H5N5S) 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.
