Chemical Structure
Description
The molecular framework of 7-Amino-6-hydroxy-6,7,8,9-tetrahydro-2,9a-diazabenzo[cd]azulen-1(2H)-one hydrochloride (C11H13N3O2HCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
