Anwendungen & Verwendung
Verwenden
Glycosaminoglycuronans react with 5-aminofluorescein to yield fluorescent derivatives. 5-aminofluorescein is also used to prepare FITC Isomer I (F-011, F-020).
Herstellung & Synthese
synthetische
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.
