CAS 2379-74-0: Japan Red 226

Description: Japan Red 226, with the CAS number 2379-74-0, is a synthetic dye belonging to the azo dye family. It is characterized by its vibrant red color, which is primarily used in various applications, including textiles, plastics, and food products. The dye is known for its excellent lightfastness and stability, making it suitable for use in environments where exposure to light is a concern. Japan Red 226 is soluble in organic solvents but has limited solubility in water, which can affect its application in different mediums. As with many azo dyes, it is important to consider its safety profile, as some azo compounds can release aromatic amines that may pose health risks. Regulatory guidelines often govern its use, particularly in food and cosmetic applications, to ensure consumer safety. Overall, Japan Red 226 is valued for its color properties and versatility, but its use must be managed in accordance with safety regulations.
