Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules with central nervous system activity. It serves as a building block in the preparation of gamma-aminobutyric acid (GABA) analogs and other neurologically active compounds. Its structure allows for functionalization at multiple sites, making it valuable in medicinal chemistry for creating libraries of compounds for drug discovery. Also utilized in the preparation of fragrances and flavoring agents due to its lactone structure, which often contributes to sweet, creamy, or fruity sensory profiles.
