Used as a key intermediate in the synthesis of high-performance polymers, particularly polyesters and polyamides, due to its ability to enhance thermal stability and mechanical properties. It is also employed in the production of liquid crystal polymers (LCPs), which are utilized in electronics, automotive components, and industrial applications for their exceptional strength and resistance to heat. Additionally, it serves as a building block in the manufacture of coatings and adhesives, providing improved durability and chemical resistance. In the pharmaceutical industry, it is used as a precursor for developing active pharmaceutical ingredients (APIs) and drug delivery systems. Its role in organic synthesis extends to creating specialty chemicals and fine chemicals for various industrial processes.
