Direct Blue 71

Description:

Direct Blue 71, with the CAS number 4399-55-7, 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 textile applications, particularly for dyeing cotton and other cellulose fibers, due to its excellent colorfastness and vibrant blue hue. Direct Blue 71 exhibits good solubility in water, making it suitable for various dyeing processes. It is known for its stability under light and heat, which contributes to its effectiveness in maintaining color during washing and exposure to environmental conditions. However, like many azo dyes, it may raise environmental and health concerns, as some azo compounds can release aromatic amines that are potentially harmful. Therefore, its use is regulated in many regions to ensure safety and minimize environmental impact. Overall, Direct Blue 71 is valued for its coloring properties in industrial applications while also necessitating careful handling and compliance with safety regulations.
