2,5-Difluoroterephthalic acid is primarily used in the synthesis of advanced polymers and materials. It serves as a key monomer in the production of high-performance polyesters and polyamides, which are valued for their thermal stability and chemical resistance. These polymers are often employed in industries such as automotive, aerospace, and electronics, where durable and lightweight materials are essential. Additionally, it is utilized in the development of metal-organic frameworks (MOFs), which have applications in gas storage, separation, and catalysis due to their porous structure and high surface area. Its fluorine atoms enhance the properties of the resulting materials, making them suitable for specialized applications.
