Ethyl 6-(((5-fluoro-2-hydroxyphenyl)(phenyl)methyl)amino)-1,3a-dihydropyrazolo[1,5-a]pyrimidine-3-carboxylate (C22H21FN4O3) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
