This chemical is primarily utilized in the synthesis of advanced polymers and resins, particularly in the production of high-performance materials. It serves as a key intermediate in the development of polyimides, which are known for their exceptional thermal stability, mechanical strength, and chemical resistance. These polyimides are widely used in electronics, such as flexible printed circuits, insulating films, and coatings for semiconductors. Additionally, it finds application in the creation of adhesives and sealants that require durability under extreme conditions, such as in aerospace and automotive industries. Its reactivity as an anhydride also makes it valuable in crosslinking processes, enhancing the properties of various industrial coatings and composites.
