C.I. Acid Yellow 17

Description:
C.I. Acid Yellow 17, also known by its CAS number 6359-98-4, is a synthetic azo dye commonly used in various applications, including textiles, food, and cosmetics. This compound is characterized by its bright yellow color, which results from the presence of azo (-N=N-) functional groups that contribute to its chromophoric properties. Acid Yellow 17 is water-soluble, making it suitable for use in aqueous dyeing processes. It exhibits good lightfastness and stability under acidic conditions, which enhances its utility in different formulations. However, like many azo dyes, it may raise concerns regarding potential health and environmental impacts, particularly due to the possibility of releasing aromatic amines upon degradation. Regulatory frameworks in various regions may impose restrictions on its use, especially in consumer products. Overall, C.I. Acid Yellow 17 is valued for its vibrant hue and versatility, but its safety profile should be carefully considered in applications involving direct human exposure.
