Product Overview

Eastman™ THQ (Toluhydroquinone) is a tan to white crystalline solid that goes through similar chemical reactions as Hydroquinone. However, due to the presence of a methyl group in the ortho position, THQ becomes a highly active inhibitor in the free radical polymerization of vinyl monomers and unsaturated polyesters.
