Key Properties
Sudan IV (M.S.) (C.I. No.26105) is a lipid-soluble azo dye primarily used for staining fats in biological samples. This compound is notable for its ability to selectively color lipids, making it a valuable tool in histology and pathology. With a minimum dye content of 80%, it is specifically designed for applications requiring high purity and solubility in alcohol. Sudan IV is commonly utilized in laboratories for the visualization of fat deposits in frozen tissue sections, serving as an alternative to other lipid stains such as Sudan III.
Also known as Biebrich Scarlet R, Scarlet Red.
