Basic Yellow 21

Description:
Basic Yellow 21, with the CAS number 6359-50-8, is a synthetic dye belonging to the class of cationic dyes, which are characterized by their positive charge. This dye is primarily used in textile applications, particularly for dyeing acrylic fibers, as well as in paper and leather industries. Basic Yellow 21 exhibits high solubility in water, making it effective for various dyeing processes. Its vibrant yellow color is attributed to the presence of specific chromophores in its molecular structure, which absorb certain wavelengths of light. The dye is known for its good lightfastness and washfastness properties, although these can vary depending on the substrate and dyeing conditions. Safety considerations are important, as cationic dyes can be irritants and may pose environmental concerns if not managed properly. Overall, Basic Yellow 21 is valued for its bright coloration and versatility in various industrial applications.
