CAS 12221-86-2: Basic Yellow 40

Description: Basic Yellow 40, also known by its chemical name as a cationic dye, is a synthetic organic compound primarily used in the textile industry for dyeing fabrics, particularly those made from acrylic and other synthetic fibers. It belongs to the class of azo dyes, characterized by the presence of one or more azo groups (-N=N-), which contribute to its vibrant yellow color. This dye is soluble in water, making it suitable for various dyeing processes. Basic Yellow 40 exhibits good lightfastness and washfastness, although its performance can vary depending on the substrate and dyeing conditions. Additionally, it is important to note that cationic dyes like Basic Yellow 40 can interact with negatively charged surfaces, which can enhance their fixation on certain materials. However, safety considerations are paramount, as some azo dyes have been associated with potential health risks, prompting regulatory scrutiny. Therefore, proper handling and adherence to safety guidelines are essential when working with this chemical substance.
