| | Solvent Red 41 Usage And Synthesis |
| Uses | Certified by the Biological Stain Commission (BSC)For In-Vitro Diagnostic Use.For Professional Use.Used for staining acid-fast bacillus in the Periodic Acid Schiff method. Chemical indicator, pH range 1.0-3.0. Color change yellow-magenta.', 'HARLECO(R) For staining acid-fast bacillus in the Periodic Acid Schiff method | | Preparation | (a) aniline, p-Methylaniline and O-Methylaniline Triethylamine hydrochloride and its mixture and 1-Nitrobenzene or 1-Nitrobenzene and 1-Methyl-2-nitrobenzene mixture, iron and Zinc chloride in the presence of heating (Zinc chloride method); (b) aniline,p-MethylanilineandO-Methylanilinemixture and Arsenic acidheating (Arsenic acidmethod). | | Definition | ChEBI: An imine that is 4-methylidenecyclohexa-2,5-dien-1-imine in which the hydrogens of the methylidene group are replaced by 4-aminophenyl and 3-methyl-4-aminophenyl groups. The monohydrochloride salt is the histological dye 'rosanilin'. | | Properties and Applications | brilliant blue light red (6-Amino-4-hydroxynaphthalene-2-sulfonic acid ). Soluble in water for red light purple, soluble in ethanol to red. In concentrated sulfuric acid for yellow brown solution, dilute almost colorless. Dye aqueous solution to join sodium hydroxide colorless, have red precipitation.
