Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) with central nervous system activity. It serves as a chiral building block in the production of certain antidepressants and antipsychotic drugs. Its strained azetidine ring enhances binding selectivity in some drug candidates. Also employed in research for novel kinase inhibitors and as a precursor in the preparation of functionalized amines for medicinal chemistry.
