Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and fine chemicals. Its reactive ester and cyclic structure make it valuable for constructing complex molecules through reactions such as Grignard additions, reductions, and cyclizations. Commonly employed in the development of fragrances and flavoring agents due to its ability to form ester-based aroma compounds. Also utilized in polymer chemistry to modify resin properties and enhance solubility in specialty coatings.
