It is characterized by its bright yellow color and is soluble in water, making it suitable for dyeing processes. The chemical structure of Acid Yellow 9 features an azo group (-N=N-) that contributes to its vibrant hue and stability. This compound is often utilized in the dyeing of protein fibers, such as silk and wool, as well as in the coloration of paper and plastics. While Acid Yellow 9 is generally considered safe for use in certain applications, it is important to note that some azo dyes can release aromatic amines, which may pose health risks.
