This chemical is primarily utilized in the synthesis of high-performance polymers and resins, particularly those requiring thermal stability and chemical resistance. It serves as a key intermediate in the production of polyethersulfones (PES), which are widely used in engineering plastics for applications such as automotive components, electrical insulation, and medical devices. Additionally, it is employed in the development of specialty coatings and adhesives that demand durability under harsh conditions. Its role in creating advanced materials makes it valuable in industries focused on innovation and high-performance solutions.
