Chemical Structure
Description
tert-Butyl 3-bromo-6,6-dimethyl-5,6-dihydroimidazo[1,5-a]pyrazine-7(8H)-carboxylate (C13H20BrN3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine 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.
