General description

4-Methoxyphenol, a 4-alkoxyphenol, can be synthesized from hydroquinone. It undergoes polymerization in the presence of horseradish peroxidase (enzymatic catalyst) and sodium dodecyl sulfate (surfactant) to afford poly(4-methoxyphenol).

Application

4-Methoxyphenol may be used in to synthesize chiral building blocks such as 1,2-diols. It also has various industrial applications, such as an antioxidant, an inhibitor for the polymerization reactions and a stabilizing agent.
