Direct Blue 67

Description:

Direct Blue 67, with the CAS number 3354-97-0, 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, due to its excellent colorfastness and vibrant blue hue. Direct Blue 67 exhibits good solubility in water, making it suitable for various dyeing processes. Its chemical structure typically includes aromatic rings, which contribute to its stability and color properties. However, like many azo dyes, it may raise environmental and health concerns, particularly regarding potential toxicity and the formation of carcinogenic amines upon degradation. Therefore, its use is often regulated in many countries. In addition to textiles, Direct Blue 67 may also find applications in other fields, such as paper and leather industries, where color application is required. Proper handling and disposal practices are essential to mitigate any associated risks.
