Chemical Structure
Description
The molecular framework of 6-Bromo-5-methyl-2-(methylthio)-[1,2,4]triazolo[1,5-a]pyrimidin-7-ol (C7H7BrN4OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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.
