Used primarily in the production of high-performance polymers, particularly as a monomer in the synthesis of liquid crystal polymers (LCPs). These polymers are valued for their exceptional thermal stability, mechanical strength, and chemical resistance, making them suitable for applications in electronics, automotive components, and industrial machinery. Additionally, it serves as a key intermediate in the manufacture of specialty chemicals and dyes, contributing to the development of advanced materials with tailored properties. Its role in enhancing the performance of polymers and other materials underscores its importance in modern industrial applications.
