CAS 2429-74-5

Direct Blue 15

Description:

Direct Blue 15, with the CAS number 2429-74-5, 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 textile applications for dyeing cotton and other cellulose fibers, as well as in paper and leather industries. Direct Blue 15 exhibits a deep blue color and is known for its good lightfastness and washfastness properties, making it suitable for various applications. The dye is soluble in water, which facilitates its use in dyeing processes. However, like many azo dyes, it may raise environmental and health concerns due to potential toxicity and the formation of aromatic amines upon degradation. Therefore, its use is regulated in some regions. Safety data sheets typically recommend handling it with care, using appropriate personal protective equipment to minimize exposure. Overall, Direct Blue 15 is a versatile dye with specific characteristics that make it valuable in industrial applications, while also necessitating careful management due to its chemical nature.

Direct Blue 15

CAS: 2429-74-5

Direct Blue 15 is a water-soluble organic dye that is used in electrochemical impedance spectroscopy for wastewater treatment. The high salt and physiological effects of Direct Blue 15 have been studied in dose groups of rats. Direct Blue 15 was not found to be carcinogenic to rats, but did cause liver lesions at high doses. However, it did not cause DNA damage or induce mutations in the calf-thymus DNA. The hydroxyl group on the molecule allows it to bind to amines, which may explain its toxicity and mutagenicity.
