Used primarily as an azo dye in textile and leather industries for coloring due to its strong color intensity and affinity for fibers. Also applied in printing inks and as a coloring agent in some specialty coatings. Its structure allows for good lightfastness and thermal stability, making it suitable for products requiring durable color. Limited use in biological staining due to its solubility and binding characteristics. Not used in food or pharmaceutical applications because of potential toxicity associated with aromatic amines.
