Acid Yellow 17 (CAS 6359-98-4)

Acid Yellow 17, with the CAS number 6359-98-4, is a synthetic azo dye characterized by its vibrant yellow hue. Azo dyes are compounds featuring one or more azo groups (–N=N–), which are typically linked between aromatic structures, and are known for their vivid colors and ability to chemically bond with textile fibers. Acid Yellow 17, specifically, is anionic in nature, making it highly soluble in water and suitable for dyeing plant-based fibers such as cotton and silk, as well as synthetic fibers under acidic conditions. The mechanism by which Acid Yellow 17 imparts color involves the formation of azo bonds that absorb specific wavelengths of visible light, reflecting wavelengths that produce the dye′s characteristic yellow color. In research, Acid Yellow 17 has been employed in studies focused on the environmental impact of azo dyes, particularly their behavior in water treatment systems and their biodegradability. Additionally, it has been used in analytical chemistry for developing colorimetric assays and sensors due to its predictable color change under various pH conditions. This has allowed researchers to utilize Acid Yellow 17 in the detection and quantification of different substances, exploring its chromatic properties in diverse scientific applications beyond its traditional textile uses.
