Used primarily as an intermediate in the synthesis of dyes and pigments, particularly for coloring textiles, paper, and leather. Its structure allows it to form stable, vibrant colors when reacted with other compounds. Additionally, it finds application in the production of fluorescent whitening agents, which are used to enhance the brightness of materials like fabrics and plastics. In research, it serves as a building block for developing more complex organic molecules with potential applications in materials science and analytical chemistry.
