CAS 12236-29-2: Disperse Yellow 39

Description: Disperse Yellow 39, with the CAS number 12236-29-2, is an organic compound primarily used as a dye in the textile industry, particularly for dyeing synthetic fibers such as polyester. It belongs to the class of disperse dyes, which are characterized by their ability to be dispersed in water and their affinity for hydrophobic materials. This dye exhibits good lightfastness and washfastness, making it suitable for applications where durability is essential. Chemically, Disperse Yellow 39 is a yellow azo dye, which means it contains an azo group (-N=N-) that contributes to its color properties. The dye is typically applied in a dispersed form, allowing it to penetrate the fibers effectively. Safety considerations are important, as some azo dyes can release aromatic amines, which may pose health risks. Therefore, handling and disposal should follow appropriate safety guidelines to minimize environmental impact and health hazards. Overall, Disperse Yellow 39 is valued for its vibrant color and performance in textile applications.
