Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. Its keto-ester functionality allows for versatile chemical transformations, such as reductions, condensations, and cyclization reactions. Commonly employed in the synthesis of bioactive molecules, including prostaglandin analogs and other medicinally relevant compounds. Also utilized in fragrance and flavor synthesis due to its reactive functional groups that can be modified to produce esters and alcohols with desirable olfactory properties.
