Descripción

Application

Metal-complexing agent

Pyrogallol undergoes quick autooxidation in alkaline solution. Due to this property, its alkaline solution is generally used for the removal of oxygen from gases. Pyrogallol may also be used to prepare pyrogallol monomethyl ether via methylation and gallacetophenone via a modified Nencki reaction.
