CAS 81-68-5

Disperse Red 86

Description:

Disperse Red 86, with the CAS number 81-68-5, is an organic compound primarily used as a dye in the textile industry, particularly for synthetic fibers such as polyester. It belongs to the class of disperse dyes, which are characterized by their ability to be dispersed in water for application on hydrophobic substrates. This dye exhibits a bright red color and is known for its good lightfastness and washfastness properties, making it suitable for various applications in dyeing and printing textiles. Chemically, Disperse Red 86 is a member of the azo dye family, which is characterized by the presence of an azo group (-N=N-) linking two aromatic rings. Its molecular structure contributes to its color properties and stability. However, like many azo dyes, it may raise environmental and health concerns due to potential toxicity and the formation of aromatic amines upon degradation. Therefore, handling and disposal of Disperse Red 86 should be conducted with care, adhering to safety regulations and guidelines.
