Used in the synthesis of dyes and pigments, particularly azo dyes, due to its aromatic amine functionality which readily undergoes diazotization and coupling reactions. It serves as an intermediate in the production of hair coloring agents and textile dyes, offering a range of shades with good color fastness. Also employed in the preparation of pharmaceuticals and agrochemicals where the ortho-aminophenol structure acts as a building block for heterocyclic compounds. Its sulfate salt form enhances stability and solubility, making it suitable for use in aqueous reaction systems. Additionally, it finds application in electroplating processes and as a corrosion inhibitor in certain industrial formulations.
