CAS 6359-82-6

Acid Yellow 11

Description:

Acid Yellow 11, with the CAS number 6359-82-6, is a synthetic azo dye commonly used in various applications, including textiles, food, and cosmetics. This dye is characterized by its bright yellow color, which is attributed to the presence of azo functional groups (-N=N-). Acid Yellow 11 is water-soluble, making it suitable for use in aqueous dyeing processes. It exhibits good lightfastness and stability under acidic conditions, which is advantageous for its application in acidic dyeing environments. However, like many azo dyes, it may raise concerns regarding environmental and health impacts, particularly due to the potential release of aromatic amines upon degradation. Therefore, its use is often regulated in many countries. In terms of chemical structure, Acid Yellow 11 typically contains sulfonic acid groups that enhance its solubility and affinity for various substrates. Overall, Acid Yellow 11 is valued for its vibrant hue and versatility, but its safety and environmental implications warrant careful consideration in its application.
