Chemical Structure
Description
3,7-Dibromodibenzothiophene 5,5-Dioxide (C12H6Br2O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
3,7-Dibromodibenzothiophene 5,5-Dioxide (CAS 83834-12-2), molecular formula C12H6Br2O2S and molecular weight 374.05 g/mol, is a CATO reference standard with documented purity and traceability.
