Chemical Structure
Description
The molecular framework of 5-(Methylthio)-2H-[1,2,3]triazolo[4,5-d]pyrimidin-7-amine (C5H6N6S) 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.
