Chemical Structure

5-(Ethylthio)-1H-1,2,4-triazol-3-amine CAS 51420-35-0 chemical structure

Description

The molecular framework of 5-(Ethylthio)-1H-1,2,4-triazol-3-amine (C4H8N4S) 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.
