Used primarily in the synthesis of dyes and pigments, it serves as a key intermediate in producing colorants for textiles and plastics. It is also employed in the manufacture of agrochemicals, where it acts as a precursor for certain herbicides and pesticides. Additionally, it finds application in organic synthesis, particularly in the preparation of naphthalene derivatives used in pharmaceuticals and research. Its role in creating fluorescent compounds is notable, making it valuable in the development of optical brighteners and sensors.
