CAS 2581-69-3

Disperse Orange 1

Description:

Disperse Orange 1, with the CAS number 2581-69-3, is an organic compound primarily used as a dye in the textile industry, particularly for synthetic fibers like polyester. It belongs to the class of disperse dyes, which are characterized by their ability to be dispersed in water rather than dissolved, allowing for effective dyeing of hydrophobic materials. This dye exhibits a bright orange color and is known for its good lightfastness and washfastness properties, making it suitable for applications where color retention is essential. Chemically, Disperse Orange 1 is an azo dye, which means it contains an azo group (-N=N-) that contributes to its chromophoric properties. While it is effective in dyeing processes, it is important to note that some azo dyes can release aromatic amines, which may pose health and environmental concerns. Therefore, safety measures and regulations are often in place regarding its use. Overall, Disperse Orange 1 is valued for its vibrant color and performance in textile applications.
