Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals. It serves as a building block for gamma-hydroxybutyric acid (GHB) analogs and other bioactive molecules. Commonly employed in the development of central nervous system agents due to its structural similarity to neurotransmitter precursors. Also utilized in the synthesis of chiral compounds where the hydroxyl and ester functionalities allow for selective transformations. Its cyclic ether structure with functional handles makes it valuable in medicinal chemistry for constructing complex lactones and heterocycles.
