CAS 6227-02-7
:Direct Red 16
Description:
Direct Red 16, with the CAS number 6227-02-7, is a synthetic azo dye commonly used in various applications, including textiles, paper, and food coloring. This dye is characterized by its vibrant red hue, which is attributed to the presence of azo groups (-N=N-) in its molecular structure. Direct Red 16 is known for its excellent lightfastness and stability, making it suitable for use in products that require durability against fading. It is soluble in water, which allows for easy application in dyeing processes. However, like many azo dyes, it may raise environmental and health concerns due to potential toxicity and the formation of aromatic amines upon degradation. Therefore, its use is often regulated in various industries. In terms of chemical properties, Direct Red 16 exhibits a relatively high molecular weight and specific absorption characteristics in the UV-Vis spectrum, which can be utilized for analytical purposes. Overall, while Direct Red 16 is valued for its coloring properties, attention to safety and environmental impact is essential in its application.
