C.I. Acid Red 357, with the CAS number 61951-36-8, 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 357 is water-soluble, making it suitable for use in aqueous dyeing processes. It exhibits good stability under normal conditions but 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 protein fibers such as silk and wool. While it is widely used, there are concerns regarding the potential health and environmental impacts of azo dyes, as some can release carcinogenic amines upon degradation. Therefore, regulatory guidelines often govern its use, particularly in consumer products. Overall, C.I. Acid Red 357 is valued for its intense coloration and versatility, but safety considerations are paramount in its application.

<p>Acid Red 357 is a basic dye, which is used in the treatment of wastewater. It binds to the surface of particles and reacts with sodium carbonate to form a hydroxide precipitate. This reaction leads to removal of colorants from the water. Acid Red 357 is also reactive, nucleophilic, and has high values for both kinetic data and transfer mechanism.</p>
