CAS 12226-38-9: remazol brilliant violet 5R

Description: Remazol Brilliant Violet 5R is a synthetic dye belonging to the class of azo dyes, characterized by its vibrant violet color. It is primarily used in textile dyeing, particularly for wool and silk, due to its excellent solubility in water and ability to form strong bonds with fibers. The chemical structure features multiple aromatic rings and azo groups, which contribute to its stability and colorfastness. This dye is known for its high affinity for protein fibers, making it suitable for applications in the textile industry. Additionally, Remazol Brilliant Violet 5R is classified as a reactive dye, meaning it can chemically react with the substrate, leading to improved wash and light fastness. However, like many azo dyes, it may raise environmental and health concerns due to potential toxicity and the formation of carcinogenic amines upon degradation. Therefore, its use is regulated in many regions, and alternatives are often sought in sustainable textile practices.
