This chemical is primarily used in the synthesis of polymers and resins, where it acts as a key intermediate. It is particularly valuable in the production of high-performance materials due to its ability to form stable and durable bonds. In the pharmaceutical industry, it serves as a building block for creating active pharmaceutical ingredients (APIs) with specific therapeutic properties. Additionally, it is utilized in organic synthesis to develop complex molecules for research and industrial applications. Its anhydride functionality makes it reactive towards amines and alcohols, enabling the formation of amides and esters, which are essential in various chemical processes.
