Used primarily as a dye intermediate in the production of azo dyes, this compound contributes to the synthesis of colored compounds for textiles, inks, and coatings. Its strong chromophoric properties make it valuable in developing dyes with intense hues, particularly in the yellow to red range. It also finds use in research settings as a model compound for studying azo coupling reactions and photoisomerization behavior due to its responsive nature to light and pH changes. Limited applications exist in analytical chemistry as a colorimetric reagent for detecting certain metal ions, where color shifts indicate presence or concentration.
