Chemical Structure
Description
tert-Butyl 6-chloro-5-nitro-3H-spiro[benzofuran-2,4'-piperidine]-1'-carboxylate (C17H21ClN2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
