 | Hazard Information | Back Directory |  | [Description] 
 
 5-AMF is a fluorescent probe for carboxylic acids and glutamine, and it also can be coupled to aldehydes and ketones. |  | [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] 
 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: 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.
 |  | [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. |
