Sudan Red 7B Chemical Properties,Usage,Production

Chemical Properties

bordeaux crystalline powder

Uses

Sudan Red 7B is a fat soluble dye. It has been used to study the effects of emulsifying agents on disposition of lipid soluble drugs included in fat emulsion. Dyes and metabolites, Environmental Testing.

Definition

ChEBI: Sudan Red 7B is a member of azobenzenes. It is effectively used to stain lipids and is used to indicate the presence of suberin in cell walls.

Preparation

4-(Phenyldiazenyl)benzenamine diazotization, and N-ethylnaphthalen-2-amine coupling.

Biological Activity

Sudan red 7B, also known as f at red, is a non-fluorescent stain. It is effectively used to stain lipids and is used to indicate the presence of suberin in cell walls. Sudan red 7B acts as a marker for formosan subterranean termite, Coptotermes fornosanus Shiraki.
Appl- Sudan Red 7B has been used to stain root sections of pearl millet.

Safety Profile

Questionable carcinogen with experimental tumorigenic data. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx.

Staining Procedures

The stain is dissolved (0.1 % w/w) in polyethylene glycol 400 glycerol (1+9). Lipids are positive. It is especially good for demonstrating the presence of suberin.

Properties and Applications

brilliant blue light red. Soluble in ethanol for cherry red, soluble in acetone and benzene. In concentrated sulfuric acid for brilliant green blue, blue purple for after diluted to bordeaux red
