Description

1,2-Naphthoquinone-4-sulfonic acid sodium salt is a fluorescent probe that reacts with the hydroxyl groups of amino acids and proteins. It has been used to measure glucose levels by injecting it into a living organism and examining the fluorescence emitted in response to an excitation wavelength. The redox potential of this molecule is -0.29 volts, which indicates that it is nucleophilic. 1,2-Naphthoquinone-4-sulfonic acid sodium salt can be used as a dye for labeling amines and other compounds with strong electron withdrawing groups. This compound is often used as a reagent in the synthesis of pharmaceutical preparations such as ceftriaxone. 1,2-Naphthoquinone-4-sulfonic acid sodium salt also reacts with hydrochloric acid to produce amines such as benzeneamine or ethylamine.
