Chemical Structure
Description
The occurrence of 4-Chloromethyl-6,8-difluoroumbelliferyl b-D-galactopyranoside is closely related to a flavonoid core, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Chloromethyl-6,8-difluoroumbelliferyl b-D-galactopyranoside (CAS 215868-46-5) is a high-purity analytical reference standard with the molecular formula C16H15ClF2O8 and a molecular weight of 408.74 g/mol.
4-Chloromethyl-6,8-difluoroumbelliferyl b-D-galactopyranoside (C16H15ClF2O8) contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine/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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
