CAS 2092-55-9: Acid Alizarin Violet N

Description: Acid Alizarin Violet N, with the CAS number 2092-55-9, is a synthetic dye belonging to the class of azo dyes. It is characterized by its vibrant violet color, which is attributed to the presence of azo functional groups (-N=N-). This compound is soluble in water, making it suitable for various applications, particularly in textile dyeing and as a pH indicator. Acid Alizarin Violet N exhibits good lightfastness and stability under acidic conditions, which enhances its utility in different formulations. Additionally, it can be used in biological staining and as a colorant in cosmetics and food products, although its use in food is subject to regulatory scrutiny due to potential health concerns associated with azo dyes. The dye's molecular structure contributes to its color properties and reactivity, making it a valuable compound in both industrial and laboratory settings. As with many synthetic dyes, safety precautions should be observed when handling Acid Alizarin Violet N, as it may pose health risks if ingested or if it comes into contact with skin.
