CAS 4197-25-5: Sudan Black

Description:Sudan Black, with the CAS number 4197-25-5, is a synthetic dye belonging to the Sudan dye family, primarily used for staining in histology and microscopy. It is characterized by its deep black color and is soluble in organic solvents such as ethanol and acetone, but insoluble in water. Sudan Black is often employed to visualize lipids in biological tissues due to its affinity for fat molecules, making it a valuable tool in biological and medical research. The dye works by binding to lipid-rich structures, allowing for enhanced contrast in microscopic examinations. However, it is important to note that Sudan Black is considered a potential carcinogen, and safety precautions should be taken when handling it. Its use is regulated in many contexts, particularly in food and consumer products, due to concerns regarding toxicity and environmental impact. Overall, Sudan Black serves as an important reagent in laboratory settings, particularly for studies involving lipid metabolism and cellular structures.
