| 5-Aminofluorescein Usage And Synthesis |
Chemical Properties | Dark Red Solid | Uses | 5-aminofluorescein is also used to prepare FITC Isomer I (CDX-F0011, CDX-F0020). It is a chemical used as molecular probe and important as fluorescent dye and for derivatives. Fluorescent labeling reagent for proteins. Used in the fluorescent antibody technique for rapid identification of pathogens. | Uses | Glycosaminoglycuronans react with 5-aminofluorescein to yield fluorescent derivatives. 5-aminofluorescein is also used to prepare FITC Isomer I (F-011, F-020). | Definition | ChEBI: 5-aminofluorescein is a primary amino compound that is fluorescein carrying an amino substituent at C-5. Building block/intermediate for the synthesis of the fluorescent dye flourescein; also used to produce N-(fluorescein-5-yl)maleamic acid. It derives from a fluorescein (lactone form). | Preparation |
The preparation of 5-aminofluorescein is carried out either by first saponification of 5-nitrofluorescein acetates with alcohol alkali, followed by reduction of the obtained 5-nitrofluorescein in a solution of alcohol alkali with hydrazine hydrate on a nickel catalyst to obtain 5-aminofluorescein , Or by boiling in an aqueous solution of sodium sulfide. The restoration of the nitro group and the saponification of acetates in the second case occurs in one stage.
| General Description | Fluoresceinamine, isomer I belongs to the class of derivatized fluoresceins. |
