Used as an intermediate in organic synthesis, particularly in the preparation of heterocyclic compounds and pharmaceuticals. Its bromoacetyl group allows for nucleophilic substitution reactions, making it valuable in the development of bioactive molecules. Commonly employed in the synthesis of indole and oxindole derivatives, which exhibit biological activities such as kinase inhibition and anti-inflammatory effects. Also utilized in medicinal chemistry for constructing enzyme inhibitors and in the design of labeled compounds for biochemical assays.
