This chemical is primarily used as an intermediate in the synthesis of dyes and pigments, particularly for textile, paper, and plastics industries. It plays a key role in producing vibrant and colorfast dyes due to its reactive sulfophenyl group, especially for fabrics and synthetic fibers, providing bright colors resistant to washing, fading, and environmental exposure. Additionally, it is utilized in the development of specialized colorants for inks and coatings, offering stability and resistance to factors like sunlight. In the paper industry, it improves color quality and printing uniformity. Its application extends to analytical chemistry, where it is employed as a reagent for detecting and quantifying specific metal ions.
