CAS 1328-51-4: C.I. Direct Blue 86

Description:C.I. Direct Blue 86, with the CAS number 1328-51-4, is a synthetic dye primarily used in the textile industry for dyeing cellulose fibers, such as cotton. It belongs to the class of direct dyes, which can be applied directly to fabrics without the need for a mordant. This dye is characterized by its deep blue color and good lightfastness, making it suitable for various applications, including paper and leather. Chemically, it is an azo dye, which means it contains one or more azo groups (-N=N-) in its structure, contributing to its vibrant color. C.I. Direct Blue 86 is soluble in water, allowing for easy application in dyeing processes. However, like many synthetic dyes, it may pose environmental concerns due to its potential toxicity and persistence in aquatic systems. Safety data sheets recommend handling it with care, as it may cause skin irritation or allergic reactions in some individuals. Overall, C.I. Direct Blue 86 is valued for its color properties but requires responsible management to mitigate environmental impacts.
