Used primarily as an intermediate in the synthesis of dyes and pigments, particularly for textile and leather industries. It plays a key role in producing azo dyes, which are valued for their vibrant colors and stability. Additionally, it is employed in the manufacture of agricultural chemicals, including herbicides and pesticides, due to its reactivity and ability to form complex organic compounds. In pharmaceutical research, it serves as a building block for developing certain active ingredients, though its use in this field is more limited. Proper handling is essential due to its potential toxicity and environmental impact.
