Used primarily as an intermediate in the synthesis of various dyes and pigments, particularly in the production of azo dyes, which are widely applied in textiles, leather, and paper industries. It also finds application in the manufacture of pharmaceuticals, where it serves as a building block for active pharmaceutical ingredients (APIs). Additionally, it is utilized in organic synthesis for creating complex molecules in research and industrial settings. Its role in corrosion inhibitors for metal protection is another notable application, especially in industrial maintenance and manufacturing processes.
