Chemical Structure
Description
Ethyl 6-fluoro-1-methyl-4-oxo-7-(pyrrolidin-1-yl)-1,4-dihydroquinoline-3-carboxylate (C17H19FN2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
