Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of gamma-aminobutyric acid (GABA) analogs such as pregabalin and gabapentin, which are used to treat neuropathic pain and epilepsy. Its structure allows for selective functionalization, making it valuable in constructing chiral molecules in asymmetric synthesis. Also employed in the preparation of bioactive heterocyclic compounds and fine chemicals in medicinal chemistry research.
