Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of analgesic and anti-inflammatory agents. It serves as a building block for compounds that modulate biological activity through aromatic nitro and amine functionalities. Commonly employed in the preparation of dyes and functionalized polymers due to its reactivity and stability in various coupling reactions. Also utilized in agrochemical research for designing herbicides and plant growth regulators. Its hydrochloride salt form enhances solubility and handling in aqueous reaction systems.
