C.I. Direct Yellow 11

Description:
C.I. Direct Yellow 11, with the CAS number 1325-37-7, is a synthetic azo dye commonly used in the textile industry for dyeing cellulose fibers, such as cotton and viscose. This compound is characterized by its bright yellow color, which is attributed to the presence of azo (-N=N-) functional groups that facilitate the absorption of visible light. It is water-soluble, allowing for easy application in dyeing processes. The dye exhibits good lightfastness and washfastness properties, making it suitable for various applications, although its performance can vary depending on the specific substrate and dyeing conditions. C.I. Direct Yellow 11 is also known for its relatively low toxicity compared to other dyes, but it is essential to handle it with care, as some azo dyes can release potentially harmful aromatic amines under certain conditions. Environmental considerations are increasingly important in the use of such dyes, prompting ongoing research into safer alternatives and improved dyeing techniques.
