C.I. Acid Red 183

Description:

C.I. Acid Red 183, with the CAS number 6408-31-7, is a synthetic azo dye commonly used in various applications, including textiles, food, and cosmetics. This compound is characterized by its vibrant red color, which is attributed to the presence of azo (-N=N-) functional groups that facilitate strong light absorption in the visible spectrum. Acid Red 183 is water-soluble, making it suitable for use in aqueous dyeing processes. It exhibits good stability under normal conditions, although it may be sensitive to light and heat, which can affect its colorfastness. The dye is typically applied in acidic conditions, which enhances its affinity for fibers such as wool and silk. Additionally, it is important to note that some azo dyes have raised environmental and health concerns due to potential degradation products that may be carcinogenic. Therefore, regulatory guidelines often govern its use, particularly in consumer products. Overall, C.I. Acid Red 183 is valued for its bright hue and versatility, but its application must be managed with consideration for safety and environmental impact.
