Description

Sudan IV is a lysochrome (fat-soluble dye) diazo dye used for the staining of lipids, triglycerides and lipoproteins on frozen paraffin sections[1].

DryPowder

Sudan IV is a bis(azo) compound that is 2-naphthol substituted at position 1 by a {2-methyl-4-[(2-methylphenyl)diazenyl]phenyl}diazenyl group. A fat-soluble dye predominantly used for demonstrating triglycerides in frozen sections, but which may also stain some protein bound lipids in paraffin sections. It has a role as a histological dye, a fluorochrome and a carcinogenic agent. It is a bis(azo) compound, a member of naphthols and a member of azobenzenes. It derives from a 2-naphthol.
