Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and biologically active compounds. Its cyclic structure and functional groups make it valuable for constructing complex molecules, such as prostaglandin analogs and other medicinally relevant cyclic frameworks. Commonly employed in ring-forming reactions and carbonyl transformations, it supports the development of chiral building blocks in asymmetric synthesis. Its ester groups allow for selective hydrolysis or reduction, enabling stepwise modification in multi-step synthetic routes.
