Disperse Blue 148

Description:
Disperse Blue 148, with the CAS number 52239-04-0, is a synthetic organic dye primarily used in the dyeing of synthetic fibers, particularly polyester. It belongs to the class of disperse dyes, which are characterized by their ability to be dispersed in water and are typically used for dyeing hydrophobic materials. This dye exhibits good lightfastness and washfastness, making it suitable for applications where durability is essential. Chemically, Disperse Blue 148 is known for its vibrant blue color and is often utilized in textile applications, including clothing and upholstery. Its molecular structure includes various functional groups that contribute to its solubility and affinity for synthetic fibers. Additionally, safety and environmental considerations are important when handling this dye, as some disperse dyes can pose health risks or environmental concerns. Proper safety measures should be taken during its use and disposal to mitigate any potential hazards.
