Disperse Red 11

Description:
Disperse Red 11, with the CAS number 2872-48-2, 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 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 applications where durability is essential. Chemically, Disperse Red 11 is an azo dye, which means it contains an azo group (-N=N-) that contributes to its chromophoric properties. The dye is typically applied through a process that involves high temperatures and pressures to ensure proper fixation onto the fibers. While it is effective for its intended uses, safety considerations are important, as some azo dyes can release aromatic amines that may pose health risks. Therefore, handling and disposal of Disperse Red 11 should follow appropriate safety guidelines to mitigate any potential environmental or health impacts.
