Used primarily as an intermediate in organic synthesis, it plays a key role in the production of pharmaceuticals, agrochemicals, and dyes. It is employed in the acylation reactions to introduce the butyryl group into various compounds, enhancing their chemical properties. In the pharmaceutical industry, it is utilized to synthesize active pharmaceutical ingredients (APIs) and other drug intermediates. Additionally, it serves as a reagent in the manufacture of perfumes and flavoring agents, contributing to the development of specific scents and tastes. Its reactivity also makes it valuable in the production of polymers and resins, where it modifies material characteristics for industrial applications.
