Used as a chiral building block in pharmaceutical synthesis, particularly in the production of antibiotics and antifungal agents. Serves as an intermediate in the manufacture of beta-hydroxy esters for fine chemicals. Employed in the preparation of biodegradable polymers and polyhydroxyalkanoate (PHA) research due to its structural similarity to natural monomers. Also utilized in flavor and fragrance formulations where a mild, fruity ester note is desired. Shows potential in metabolic studies and as a precursor in ketone body research.
