  • Product Details


Toluhydroquinone THQ (CAS 95-71-6) is a tan to white crystalline solid. THQ undergoes chemical reactions similarto those of hydroquinone. The presence of a methyl group in the ortho position in the toluhydroquinone molecule accounts for the slight structural and behavioral differences between toluhydroquinone and hydroquinone. Toluhydroquinone is a highly active inhibitor in the free radical polymerization of vinyl monomers and unsaturated polyesters.
