CAS 12220-28-9: Acid Red 289

Description: Acid Red 289, with the CAS number 12220-28-9, is a synthetic azo dye commonly used in various applications, including textiles, food, and cosmetics. It is characterized by its vibrant red color, which is attributed to the presence of azo functional groups (-N=N-). This compound is water-soluble, allowing it to be easily incorporated into aqueous solutions for dyeing processes. Acid Red 289 exhibits good lightfastness and stability under acidic conditions, making it suitable for use in environments where pH may vary. However, like many azo dyes, it may raise environmental and health concerns due to potential toxicity and the formation of aromatic amines upon degradation. Therefore, its use is often regulated in many countries. In terms of chemical structure, Acid Red 289 contains multiple functional groups that contribute to its dyeing properties and reactivity. Overall, while Acid Red 289 is valued for its coloring properties, careful consideration of its environmental impact and safety profile is essential in its application.
