Key Properties
Sudan IV stain solution (scarlet red solution) is a ready-made preparation of the dye, designed for direct lipid-staining applications. This solution is particularly notable for its ability to selectively stain lipids, making it an essential tool in histology and pathology. The dye, Sudan IV, is a member of the azo dye family and is widely used in biological staining protocols. Its vivid scarlet color provides high contrast against tissue sections, facilitating the visualization of fat deposits in various biological samples.
Also known as Scarlet Red Solution.

Sudan IV stain solution appears as a dark red liquid. It has a density of approximately 1.1 g/cm³ and is soluble in organic solvents such as ethanol and acetone, but insoluble in water. The solution has a characteristic odor typical of organic dyes. The boiling point of Sudan IV is around 360 °C, while the melting point of the pure dye is approximately 190 °C. The solution is stable under normal conditions but should be stored away from light to prevent degradation.
