Reactive Yellow 2

Description:
Reactive Yellow 2, with the CAS number 50662-99-2, is a synthetic dye belonging to the class of reactive dyes, which are widely used in textile applications for dyeing cellulose fibers such as cotton. This dye is characterized by its ability to form covalent bonds with the fiber, resulting in excellent wash and light fastness properties. Reactive Yellow 2 typically exhibits a bright yellow hue and is soluble in water, making it suitable for various dyeing processes. The dye's reactivity is primarily due to the presence of reactive functional groups, which facilitate the bonding with the hydroxyl groups in cellulose. In addition to its textile applications, Reactive Yellow 2 may also be used in other industries, such as paper and leather. However, it is important to handle this dye with care, as some reactive dyes can pose environmental and health risks if not managed properly. Overall, Reactive Yellow 2 is valued for its vibrant color and strong affinity for natural fibers, contributing to its popularity in the dyeing industry.
