Sudan Red 7B (N-ethyl-1-[(4-phenyldiazenylphenyl)diazenyl]naphthalen-2-amine), also called "fat red" is a member of the Sudan family of hydrophobic lipid-staining dyes. Sudan dyes are a group of lipid soluble solvent dyes often called lysochromes, in structural classification they are diazo dyes. With the use of certain solvents, may also be used to stain some protein bound lipids in paraffin sections. Sudan Red 7B has also been used to stain suberin lamellae in plant tissues.
