2-Methylhydroquinone Consensus Reports

Reported in EPA TSCA Inventory.

2-Methylhydroquinone Specification

2-Methylhydroquinone, with the CAS NO.95-71-6, is also called 2,5-Dihydroxytoluene; THQ; Toluhydroquinone; methyl hydroquinone; 2-Methylhydroquinone; P-toluhydroquinone; 2-Methyl Hydroquinone. It belongs to the Product Categories of Intermediates of Dyes and Pigments; Anthraquinones, Hydroquinones and Quinones; Building Blocks; Chemical Synthesis; Organic Building Blocks; Oxygen Compounds; Polyols. 2-Methylhydroquinone is a tan to white crystalline solid. 2-Methylhydroquinone undergoes chemical reactions similar to 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. 2-Methylhydroquinone is a highly active inhibitor in the free radical polymerization of vinyl monomers and unsaturated polyesters.
