CAS 12222-04-7: Direct Blue 199

Description:Direct Blue 199, with the CAS number 12222-04-7, is a synthetic dye belonging to the class of azo dyes, which are characterized by the presence of one or more azo groups (-N=N-). This dye is primarily used in the textile industry for dyeing cellulose fibers, such as cotton and viscose, due to its excellent colorfastness and vibrant blue hue. Direct Blue 199 is water-soluble, making it suitable for various dyeing processes, including exhaust and continuous dyeing methods. The dye exhibits good lightfastness and washfastness, which are essential properties for maintaining color integrity during laundering and exposure to light. However, like many azo dyes, it may raise environmental and health concerns, as some azo compounds can release carcinogenic amines under certain conditions. Therefore, its use is regulated in many regions, and alternatives are often sought in sustainable textile practices. Overall, Direct Blue 199 is valued for its color properties but must be handled with consideration of safety and environmental impact.
