Chemical Structure
Description
The molecular framework of 2-(4H-1,2,4-Triazol-4-yl)-2,3,3a,4,7,7a-hexahydro-1H-isoindole-1,3-dione (C10H10N4O2) is characterized by an amino-acid-derived structure, an amide 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.
