Chemical Structure
Description
methyl 1-(4-chlorobenzyl)-6-cyclopropyl-3-methyl-1H-pyrazolo[3,4-b]pyridine-4-carboxylate (C19H18ClN3O2) contains a steroid 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).
