4',5'-DIBROMOFLUORESCEIN Usage And Synthesis
Chemical Propertiesorange powder
Uses4'',5''-Dibromofluorescein is a stain with an absorption maximum of 450 nm. Dyes and metabolites, Environmental Testing
PreparationFluorescein (C.I. Acid Yellow 73, C.I. 45350) in the sodium hydroxide solution two bromination, and??made into a free acid form.
Safety ProfilePoison by ingestion and intravenous routes. An herbicide. When heated to decomposition it emits highly toxic fumes of NOx, CN-, and Br-. See also NITRILES.
Purification MethodsCrystallise it from aqueous 30% EtOH. [Beilstein 19/6 V 462.]
Properties and Applicationsbrilliant yellow light yellow. Slightly soluble in water for orange, with weak yellow fluorescence, soluble in ethanol for orange, with green yellow fluorescence, soluble in acetone peachblossom, with yellow fluorescence, soluble in Tetrahydrofurfuryl alcohol. In concentrated sulfuric acid to red light yellow, dilution after yellow brown, with orange precipitation. Dye aqueous solution to join sodium hydroxide as red edge; In the glycerol and liquid paraffin in good dispersibility. Used in medicines and cosmetics coloring.
