EOSIN METHYLENE-BLUE Usage And Synthesis
Uses
May-Grünwald solution (Eosin – methylene blue solution) is used with Giemsa stain for histological staining of blood cells.
Preparation
Fluorescein (C.I. Acid Yellow 73, C.I. 45350) in water or ethanol solution bromide into four bromine derivatives, and then into sodium salt, then product (C.I. Acid Red 87) Metaclazepam change and translated into sylvine.
Properties and Applications
brilliant blue light red. Soluble in hot water for cherry red, soluble in ethanol aqueous solution to red, with brown light yellow fluorescence. In concentrated sulfuric acid to yellow, dilution after brown light yellow precipitation. Dye aqueous solution to join sodium hydroxide as dark solution, with green fluorescence.
