This chemical is primarily used in the synthesis of polymers and advanced materials due to its bifunctional carboxylic acid groups, which allow for versatile chemical reactions. It serves as a key intermediate in the production of high-performance polyesters and polyamides, which are essential in industries requiring durable and heat-resistant materials, such as automotive and aerospace. Additionally, its tetrahydro-2H-pyran-2-yl group provides protective functionality during complex organic syntheses, enabling the creation of specialized compounds in pharmaceutical research. Its application is also seen in the development of coatings and adhesives, where its structural properties enhance performance and stability.
