| | CRYSTAL PONCEAU 6R Usage And Synthesis |
| Uses | Crystal Ponceau 6R can be used as analyte in analytical study for determination of 36 artificial pigments in foods by ultra high performance liquid chromatography and time-of-fight mass spectrometry. Dyes and metabolites, Environmental Testing | | Preparation | Naphthalen-1-amine diazo, and 7-Hydroxynaphthalene-1,3-disulfonic acid coupling. | | Definition | ChEBI: An organic sodium salt that is the disodium salt of 7-hydroxy-8-[(naphthalen-1-yl)diazenyl]naphthalene-1,3-disulfonic acid. | | Biological Activity | Crystal Ponceau 6R is mainly used in the MSB (martius yellow–crystal scarlet–methyl blue) staining procedure for the staining of connective tissue and fibrin. | | Properties and Applications | red. Soluble in water for red, soluble in ethanol for yellow light red, almost insoluble in acetone. The strong sulfuric acid for red light blue, diluted for scarlet. In water solution to join hydrochloric acid colour and lustre is darker, and extra a flake crystallization precipitation part; Add thick sodium hydroxide solution for yellow brown.
