CAS 95-71-6 Toluhydroquinone THQ 99.5%
Product Name: 2,5-dihydroxytoluene
CAS: 95-71-6
Molecular Formula: C7H8O2
Molecular Weight: 124.137
Synonyms: 2-Methylhydroquinone;THQ
Toluhydroquinone THQ 99.5% 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.
