Used as an intermediate in organic synthesis, particularly in the preparation of bioactive compounds and fragrances. Its keto-ester functionality allows for versatile chemical transformations, such as reduction, condensation, and cyclization reactions. Commonly employed in the development of flavor and fragrance ingredients due to its ability to undergo controlled degradation or modification to release odor-active molecules. Also investigated as a building block in the synthesis of biodegradable polymers and functional materials.
