CAS 5413-75-2

Acid Red 73

Description:

Acid Red 73, with the CAS number 5413-75-2, 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, making it suitable for dyeing processes that require aqueous solutions. Acid Red 73 exhibits good lightfastness and stability under acidic conditions, which enhances its utility in different formulations. However, like many azo dyes, it may raise concerns regarding environmental and health impacts, as some azo compounds can release aromatic amines that are potentially carcinogenic. Therefore, its use is often regulated in many countries. In terms of chemical structure, Acid Red 73 typically contains sulfonic acid groups, which contribute to its solubility and affinity for various substrates. Overall, Acid Red 73 is a versatile dye with specific characteristics that make it valuable in industrial applications, while also necessitating careful handling and regulatory compliance.
