Sudan Black B, powder for microbiology, 10g CAS Number: 4197-25-5 Empirical Formula: C29H24N6 Molecular Weight: 456.54 IUPAC Name: (2,2-dimethyl-1,3-dihydroperimidin-6-yl)-(4-phenylazo-1-naphthyl)diazene Structural Formula: Sudan Black B is a nonfluorescent, relatively thermostable lysochrome (fat-soluble dye) diazo dye used for staining of neutral triglycerides and lipids on frozen sections and some lipoproteins on paraffin sections. It has the appearance of a dark brown to black powder with maximum absorption at 596-605 nm and melting point 120–124 °C. It stains blue-black. Sudan Black B is one of the dyes used for Sudan staining. Similar dyes include Oil Red O, Sudan III and Sudan IV. A use of Sudan Black B is in fingerprint enhancement. It is useful for detecting fats that are contaminated with oil and grease. In differentiating haematological disorders Sudan black will stain myeloblasts but not lymphoblasts.
