Used primarily in the production of high-performance polymers, particularly aramid fibers, which are known for their exceptional strength and heat resistance. These fibers are widely utilized in the manufacturing of protective clothing, such as firefighter gear and military uniforms, as well as in industrial applications like reinforced composites for aerospace and automotive components. Additionally, it serves as an intermediate in the synthesis of dyes and pigments, contributing to the coloration of textiles and plastics. Its role in enhancing material durability and performance makes it valuable in advanced technical applications.
