MSDS Toluhydroquinone.pdfWe are very happy to introduce you Toluhydroquinone THQ CAS 95-71-6 which is our key product since from 2001. TNJ Chemical is the top supplier of Toluhydroquinone from China for more than 15 year.If you want to buy Toluhydroquinone THQ ,please contact sales22@tnjchem.com
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.
