C.I. Acid Red 97

Description:

C.I. Acid Red 97, with the CAS number 10169-02-5, is a synthetic azo dye commonly used in various applications, including textiles, food, and cosmetics. This dye is characterized by its vibrant red color and is soluble in water, making it suitable for dyeing processes that require aqueous solutions. The chemical structure of Acid Red 97 features an azo group (-N=N-) which is responsible for its color properties, as well as sulfonic acid groups that enhance its solubility. It is known for its good lightfastness and stability under acidic conditions, although it may be less stable in alkaline environments. Acid Red 97 is subject to regulatory scrutiny due to potential health concerns associated with azo dyes, particularly regarding their breakdown products, some of which may be carcinogenic. Therefore, its use is often regulated in consumer products, necessitating adherence to safety guidelines and regulations. Overall, C.I. Acid Red 97 is a versatile dye with significant industrial applications, but its safety profile requires careful consideration.
