Description

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.

2-[(4-methyl-4h-1,2,4-triazol-3-yl)sulfanyl]acetic acid (CAS 200816-06-4) is a high-purity analytical reference standard with the molecular formula C5H7N3O2S and a molecular weight of 173.19 g/mol.

The molecular framework of 2-[(4-methyl-4h-1,2,4-triazol-3-yl)sulfanyl]acetic acid (C5H7N3O2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
