Used primarily as a dye intermediate in the synthesis of azo dyes, this compound contributes to the production of colored compounds for textiles, inks, and coatings. Its strong chromophoric properties make it valuable in developing dyes with intense hues, particularly in yellow, orange, and red shades. It may also serve as a reagent in analytical chemistry for detection of certain metal ions due to its color-changing behavior under different pH or complexation conditions. Limited use in research settings involves studying azo compound stability and photoisomerization behavior. Due to potential toxicity and mutagenic concerns, its application is typically restricted to controlled industrial and laboratory environments.
