The Uses of 5-Aminofluorescein

Glycosaminoglycuronans react with 5-aminofluorescein to yield fluorescent derivatives. 5-aminofluorescein is also used to prepare FITC Isomer I (F-011, F-020).

The Uses of 5-Aminofluorescein

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.

What are the applications of Application

Fluoresceinamine, isomer I is a reagent for fluorescence studies

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.
