Chemical Structure
Description
tert-Butyl (4-chloro-3-methoxy-1-oxo-1H-isochromen-7-yl)carbamate (C15H16ClNO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
tert-Butyl (4-chloro-3-methoxy-1-oxo-1H-isochromen-7-yl)carbamate (CAS 1422968-79-3) is a high-purity analytical reference standard with the molecular formula C15H16ClNO5 and a molecular weight of 325.74 g/mol.
