Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) active agents. Its rigid cyclopentane backbone with functional groups in close proximity makes it valuable for constructing bioactive molecules. Commonly employed in the preparation of gamma-aminobutyric acid (GABA) analogs and other neurologically targeted compounds. Also utilized in the creation of chiral building blocks for drug discovery due to its stereochemical stability and derivatization potential.
