Used primarily as an intermediate in the synthesis of dyes and pigments, especially in the production of azo dyes for textiles and inks. Its structure allows for coupling reactions that yield stable, vibrant colorants. Also employed in the development of functional organic materials, including photochromic and electroactive compounds. In research, it serves as a building block for more complex molecules in medicinal chemistry, particularly in routes involving nitroaromatic transformations or bromo-directed metal-catalyzed couplings.
