Chemical Structure

2-bromo-1-(4-hydroxy-2,2,6,6-tetramethyloxan-4-yl)ethan-1-one CAS 1657017-16-7 chemical structure

Description

2-bromo-1-(4-hydroxy-2,2,6,6-tetramethyloxan-4-yl)ethan-1-one (C11H19BrO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
