Fat-soluble diazo dye primarily used for staining of neutral triglycerides and lipids. Sudan dyes are a group of lipid soluble dyes often called lysochromes. Sudan Black B is not as lipid-specific as some of the other Sudan dyes and may be useful to stain other materials. Useful for detecting fats that are contaminated with oil and grease. Used in the study of haematological disorders as it will stain myeloblasts, but not lymphoblasts.
