2,4'-Dibromoacetophenone is used as a reagent for analysis of fatty acids by HPLC as 4-bromophenacyl esters, for use in the protection of phenols and carboxylic acids. It undergoes condensation reactions with aldehydes in the presence of SnCl2 or SmI3 to afford α,β-unsaturated ketones. It is also useful in the esterification of carboxylic acids.
