Used as an intermediate in the synthesis of dyes and pharmaceuticals. Plays a role in the development of certain azo dyes due to its aromatic amine functionality, which allows for diazotization and coupling reactions. Also utilized in the preparation of local anesthetics and anti-inflammatory agents in medicinal chemistry. Its solubility in water makes it suitable for reactions in aqueous media. Additionally, it serves as a building block in organic synthesis for creating more complex aromatic compounds.
