CAS 2734-52-3

Disperse Red 19

Description:

Disperse Red 19, with the CAS number 2734-52-3, is an organic dye primarily used in the textile industry for dyeing synthetic fibers, particularly polyester. It belongs to the class of disperse dyes, which are characterized by their ability to be dispersed in water and their application in dyeing hydrophobic materials. This dye exhibits a bright red color and is known for its good lightfastness and washfastness properties, making it suitable for various applications in textiles. Chemically, Disperse Red 19 is an azo dye, which means it contains an azo group (-N=N-) that contributes to its color properties. It is important to handle this substance with care, as some azo dyes can release aromatic amines, which may pose health risks. Additionally, environmental considerations are crucial, as the disposal of dye effluents can impact aquatic ecosystems. Overall, Disperse Red 19 is valued for its vibrant coloration and performance in dyeing processes, while also necessitating responsible usage and management.
