Chemical Structure
Description
The molecular framework of 1,3-Dimethyl-1H-pyrazolo[3,4-d]pyridazin-4(5H)-one (C7H8N4O) is characterized by an amide group, a hydroxyl group, an ether linkage, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
