CAS 603-45-2: Aurin

Description: Aurin, with the CAS number 603-45-2, is an organic compound classified as a dye, specifically a type of azo dye. It is characterized by its vibrant yellow to orange color, which is attributed to the presence of azo (-N=N-) functional groups in its molecular structure. Aurin is soluble in organic solvents and exhibits limited solubility in water, making it useful in various applications, including textiles and biological staining. The compound is known for its stability under normal conditions, although it may degrade under extreme pH or light exposure. Aurin can also exhibit fluorescence, which enhances its utility in certain analytical and imaging techniques. However, like many azo dyes, it may pose environmental and health risks, as some azo compounds can release carcinogenic amines upon degradation. Therefore, handling Aurin requires appropriate safety measures to mitigate potential hazards. Overall, Aurin serves as an important compound in both industrial and research settings, particularly in the fields of chemistry and biology.
