Chemical Structure
Description
The molecular framework of 3-Amino-6-phenyl-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one (C20H17ClN4O3S) is characterized by a steroid core, an amide group, a sulfone 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
