Methyl 3-bromobenzoate is used as a reagent in organic synthesis. It is used in the synthesis of tetrahydro dibenzazocine, which acts as an inhibitor of 17beta-hydroxysteroid dehydrogenase type 3. Further, it is used to prepare 3-tert-butylphosphanyl-benzoic acid methyl ester by reacting with tert-butyltrimethylsilylphosphine.
