Used primarily in the production of dyes and pigments, it is a key intermediate in synthesizing various colorants for textiles, leather, and paper. It also finds application in the manufacture of polyurethane foams, where it acts as a chain extender or crosslinking agent, enhancing the material's mechanical properties. Additionally, it is employed in the synthesis of certain pharmaceuticals and agrochemicals, contributing to the development of active ingredients. Its role in corrosion inhibitors for metals is another notable application, helping to protect industrial equipment and infrastructure.
