CAS 915-67-3: C.I. Acid Red 27
Description:C.I. Acid Red 27, with the CAS number 915-67-3, 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 groups (-N=N-), a feature typical of many synthetic dyes. It is water-soluble, making it suitable for applications where solubility is essential. The dye exhibits good lightfastness and stability under acidic conditions, although its stability can vary depending on the specific formulation and environmental factors. C.I. Acid Red 27 is often utilized in the dyeing of protein fibers, such as silk and wool, as well as in the coloration of certain food products, although its use in food is subject to regulatory scrutiny in various regions. Safety assessments indicate that while it is generally considered safe for use in regulated applications, it may pose health risks if ingested or if it comes into prolonged contact with skin. Proper handling and adherence to safety guidelines are recommended when working with this chemical.
