Hydroxyquinol is a benzenetriol.

Production

Hydroxyquinol is produced by various means of degradation. Historically hydroxyquinol was produced by the action of potassium hydroxide on hydroquinone.[1] Today the chemical is more conveniently synthesized by dehydrating D-fructose with supercritical water:[2][3]

C6H12O6 → 3 H2O + C6H6O3

Natural Occurrence

Hydroxyquinol commonly occurs in nature as a biodegradation product of catechin, a natural phenol found in plants such as Bradyrhizobium japonicum.[4] Hydroxyquinol is also a metabolite in some organisms. For instance, Hydroxyquinol 1,2-dioxygenase is an enzyme that uses hydroxyquinol as a substrate with oxygen to produce 3-hydroxy-cis,cis-muconate.
