5-Carboxyfluorescein Chemical Properties,Uses,Production

Chemical Properties

Orange Solid

Uses

A useful reagent for the preparation of hydrolytically stable fluorescent conjugates and is a useful starting material for the synthesis of other fluorescein-derives reagent

Uses

Derivative of fluorescein giving stable derivative upon conjugation with biopolymers.

Uses

5-Carboxyfluorescein is a single isomer derivative of 5(6)-carboxyfluorescein that can be used to fluorescently label biomolecules through the interaction of carboxylic acid with primary amines. It demonstrates excitation/emission maxima of 492 and 518 nm, respectively.
