CAS 8064-60-6
:C.I. Direct Yellow 59
Description:
C.I. Direct Yellow 59, with the CAS number 8064-60-6, is a synthetic azo dye commonly used in the textile industry for dyeing cellulose fibers, such as cotton and rayon. This dye is characterized by its bright yellow color and good lightfastness, making it suitable for various applications, including paper and leather. It is soluble in water, which allows for easy application in dyeing processes. However, like many azo dyes, it may raise environmental and health concerns due to potential degradation products that can be harmful. The dye's chemical structure typically includes azo (-N=N-) linkages, which are responsible for its vibrant coloration. Safety data sheets indicate that it should be handled with care, as it may cause skin irritation or allergic reactions in some individuals. Overall, C.I. Direct Yellow 59 is valued for its coloring properties but requires responsible use and disposal to mitigate any environmental impact.
