PRODUCT INTRODUCTION
description
Sudan III is a bis(azo) compound that is 2-naphthol substituted at position 1 by a 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 fluorochrome, a histological dye and a carcinogenic agent. It is a member of azobenzenes, a bis(azo) compound and a member of naphthols. It is functionally related to a 2-naphthol.
