Storage Condition: Store in sealed containers at cool and dry place; Protect from light and moisture. Methyl 3-Bromobenzoate (CAS 618-89-3) is an halogenated benzoate derivative used as a reagent in organic synthesis. Methyl 3-Bromobenzoate is used in the synthesis of a novel series of tetrahydro dibenzazocine as inhibitors of 17β-hydroxysteroid dehydrogenase type 3. Further, it is used to prepare 3-tert-butylphosphanyl-benzoic acid methyl ester by reacting with tert-butyltrimethylsilylphosphine.
