Used as a key intermediate in organic synthesis, particularly in pharmaceutical and agrochemical manufacturing. Its bromo functional group allows for cross-coupling reactions, enabling the construction of complex carbon skeletons. Commonly employed in the preparation of beta-substituted carbonyl compounds through alkylation or metal-catalyzed transformations. The ester group can be easily hydrolyzed or reduced, offering versatility for further derivatization. Frequently utilized in the synthesis of bioactive molecules, including enzyme inhibitors and natural product analogs.
