Chemical Structure
Description
The molecular framework of 4-(2-Bromobenzoyl)-8-tert-Butyl-1-oxa-4-azaspiro[4.5]decane-3-carboxylic acid (C20H26BrNO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine 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).
