Basic Info
Sulfanilic Acid is an organic compound with amino and sulfonic acid groups, with the chemical formula C6H7NO3S. It is often used as an intermediate in dyes, pigments, and chemical synthesis, especially in the production of azo dyes. Due to the sulfonic acid group in its molecular structure, it has good water solubility. At the same time, it is also an important raw material in the synthesis of some medicines and pesticides.
