Acid Yellow 38(CAT: M053348), also known as C.I. 10335, is a synthetic azo dye commonly used in textiles, leather, paper, and some food products. It is part of the acid dye class, meaning it is water-soluble and binds to materials through ionic bonds, typically used to dye wool, silk, and nylon. Acid Yellow 38 is valued for its vibrant yellow color and ease of application in industrial dyeing processes. In research, it is studied for its environmental impact, as many azo dyes can be challenging to degrade and may contribute to water pollution, making it a target for studies on sustainable dyeing methods and biodegradation.
