This chemical is primarily used as a dye intermediate in the textile industry, where it contributes to the production of vibrant and durable colorants for fabrics. Its azo group makes it suitable for creating a range of colors, particularly in the synthesis of acid and disperse dyes. Additionally, it finds applications in the development of pH indicators due to its ability to change color in response to varying pH levels. In research, it is utilized in studies related to molecular recognition and dye-sensitized solar cells, where its photophysical properties are explored for energy conversion efficiency. Its hydroxyl and carboxylic acid functional groups also make it a candidate for further chemical modifications in organic synthesis.
