CAS 3051-11-4

Direct Yellow 4

Description:

Direct Yellow 4, with the CAS number 3051-11-4, is a synthetic azo dye commonly used in the textile industry for dyeing cellulose fibers. It is characterized by its bright yellow color and is soluble in water, making it suitable for various dyeing processes. The chemical structure of Direct Yellow 4 features azo (-N=N-) linkages, which are typical of many azo dyes, contributing to its color properties. This dye is known for its good lightfastness and washfastness, although its performance can vary depending on the specific application and conditions. Direct Yellow 4 is also utilized in other applications, including paper and food industries, although its use in food is subject to regulatory scrutiny due to potential health concerns associated with azo dyes. As with many synthetic dyes, safety considerations are important, and it is essential to handle it with appropriate precautions to minimize exposure. Overall, Direct Yellow 4 is a versatile dye with significant industrial applications, particularly in textiles.
