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 is functionally related to a 2-naphthol."}]
