Used as a dye in various industries, particularly in textiles, for coloring fabrics due to its vibrant and stable color properties. It is also employed in the production of inks and coatings, where its azo group contributes to strong coloration and durability. In analytical chemistry, it serves as a pH indicator, changing color in response to acidity or alkalinity. Additionally, it finds application in research laboratories as a reagent for studying azo compounds and their reactions.
