Used primarily as an intermediate in the synthesis of pharmaceuticals and fine chemicals. Its keto-ester functionality makes it valuable in organic reactions, particularly in the development of active pharmaceutical ingredients (APIs) where functional group versatility is required. It serves as a building block in the preparation of complex molecules, including those with biological activity. Also finds use in fragrance chemistry due to its ester nature, contributing to the creation of specialty aroma compounds. Its structure allows for further transformations such as reduction, alkylation, and condensation, enhancing its utility in synthetic pathways.
