Sudan dyes and para red in food. | [Uses]
Sudan dyes and para red in food. Dyes and metabolites, Environmental Testing. | [Preparation]
O-Anisidine diazotization, and Naphthalen-2-ol coupling. | [General Description]
Sudan dyes are classified under the azo dyes group of organic compounds that are commonly utilized as additive materials for industrial and scientific applications. | [Properties and Applications]
red to yellow red orange. Appearance is red to yellow red orange powder, the products by glacial acetic acid crystallization melting point 180 ℃. Soluble in boiling ethanol to red. Light fastness is poorer, in 110 ℃ when stability. In concentrated sulfuric acid for deep red, dilution after dark red precipitation. The alcohol solution to join hydrochloric acid for wine red; Add sodium hydroxide as orange. Mainly used in oil, wax and cultural and educational supplies coloring.
