C.I. Direct Red 83:1, with the CAS number 90880-77-6, is a synthetic azo dye commonly used in various applications, particularly in textiles and paper. This dye is characterized by its vibrant red color, which is attributed to the presence of azo functional groups (-N=N-). It exhibits good solubility in water, making it suitable for direct dyeing processes. The dye is known for its moderate to good lightfastness and washfastness properties, although these can vary depending on the substrate and conditions of use. C.I. Direct Red 83:1 is often utilized in the dyeing of cotton, wool, and other natural fibers, as well as in some synthetic materials. Safety considerations are important, as azo dyes can release aromatic amines under certain conditions, which may pose health risks. Therefore, regulatory guidelines often govern its use, particularly in consumer products. Overall, C.I. Direct Red 83:1 is valued for its color strength and versatility in various dyeing applications.

<p>C.I.Direct Red 83:1 is a dye that has been used in wastewater treatment to remove color. It is a polymerized dye that has been shown to be more efficient than the decolouration process, which is the traditional method of removing color from wastewater. The light source for this process must be within the range of 350-500 nm and at least 100 mW/cm2 intensity. This dye has also been shown to be an effective photolysis agent for organic compounds such as phenols, amines, and sulfides.</p>
