Used primarily as a key intermediate in the synthesis of advanced materials, particularly in the production of liquid crystal polymers and high-performance polyesters. Its rigid structure contributes to the thermal stability and mechanical strength of these materials, making them suitable for applications in electronics, automotive components, and aerospace engineering. Additionally, it serves as a building block in the development of metal-organic frameworks (MOFs), which are utilized in gas storage, separation, and catalysis due to their porous and customizable structures. Its role in organic synthesis also extends to the creation of dyes, pigments, and pharmaceutical compounds.
