Chemical Structure
Description
1031319-77-3 4-(4-chlorophenyl)-2-{[3-(diethylamino)propyl]amino}-4-oxobutanoic acid KS-00003LR4 (C17H25ClN2O3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
