Acid Red 266

Description:

Acid Red 266, with the CAS number 57741-47-6, 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 dye is water-soluble, making it suitable for use in aqueous solutions. Acid Red 266 exhibits good lightfastness and stability under acidic conditions, which enhances its utility in dyeing processes. However, like many azo dyes, it may raise environmental and health concerns due to potential degradation products that can be harmful. Its chemical structure typically includes aromatic rings, contributing to its color properties and reactivity. When handling Acid Red 266, it is essential to follow safety guidelines to minimize exposure, as some azo dyes have been associated with allergic reactions or other health risks. Overall, Acid Red 266 is a versatile dye with specific characteristics that make it valuable in various industrial applications.

Acid Red 266

CAS: 57741-47-6

Acid Red 266 is a hydroxyl-containing polymeric dye that is used in the textile and paper industries as a colorant, pigment, or dye. It has been shown to be an efficient control agent for the polymerization of polyvinyl acetate. Acid Red 266 can also be used to form films with high light stability and good mechanical properties. The hydroxyl group present in this molecule causes it to have a polarizing effect on UV absorption. Acid Red 266 is made of particles that are soluble in water and alcohols, but insoluble in oils. This acid dye is also sensitive to heat, so it should not be exposed to temperatures over 60°C.
