Used primarily as an intermediate in the synthesis of dyes and pigments, particularly for coloring textiles, plastics, and paper. It plays a key role in producing vat dyes, which are known for their excellent color fastness and resistance to fading. Additionally, it is utilized in the manufacturing of photoreactive compounds for use in photolithography and other light-sensitive applications. Its stability and ability to form complex structures make it valuable in advanced material research and organic synthesis.
