Used primarily as a building block in organic synthesis, especially in the preparation of pharmaceuticals and biologically active compounds. It serves as an intermediate in the development of drugs targeting neurological and psychiatric disorders due to the presence of the chlorophenyl group, which can influence binding to central nervous system receptors. Also utilized in the synthesis of peptidomimetics and enzyme inhibitors, where the chlorine substituent enhances metabolic stability and modulates lipophilicity. Its chiral nature allows for studies in asymmetric synthesis and resolution techniques.
