CAS 2602-46-2: DIRECT BLUE 6

Description:Direct Blue 6, with the CAS number 2602-46-2, is a synthetic dye belonging to the class of azo dyes, which are characterized by the presence of one or more azo groups (-N=N-). This dye is primarily used in the textile industry for dyeing cotton and other cellulose fibers, providing a deep blue color. It is water-soluble, which enhances its application in various aqueous dyeing processes. Direct Blue 6 exhibits good lightfastness and washfastness properties, making it suitable for use in products that require durability. However, like many azo dyes, it may pose environmental and health concerns due to the potential release of aromatic amines upon degradation. Safety data sheets typically recommend handling it with care, as it may cause skin irritation or allergic reactions in sensitive individuals. Regulatory frameworks in various regions may impose restrictions on its use due to these concerns, emphasizing the importance of proper handling and disposal practices in industrial applications.
