2-Methylhydroquinone Chemical Properties,Usage,Production

Chemical Properties

white solid

Uses

Antioxidant, polymerization inhibitor.

Uses

Methylhydroquinone is used as stabilizer and antioxidant in aerylic monomers to prevent polymerization.

Uses

Methylhydroquinone is a marine fungus metabolite, showing activity as an angiosupressor that interferes with the Akt pathway. Allows for screening of novel inhibitors of angiogenesis.

Definition

ChEBI: A member of the class of hydroquinones that is hydroquinone in which one of the benzene hydrogens has been replaced by a methyl group.

Tetrahedron Letters, 22, p. 2337, 1981 DOI: 10.1016/S0040-4039(01)82900-2

General Description

Methylhydroquinone is produced by the oxidation of o-cresol by the mutants G103S, G103S/A107G, and G103S/A107T.

Flammability and Explosibility

Not classified

Biochem/physiol Actions

Methylhydroquinone (Toluquinol) inhibits the growth of endothelial and tumor cells in culture in the micromolar range and is a promising drug candidate in the treatment of cancer and other angiogenesis-related pathologies.

Purification Methods

Crystallise the quinone from EtOH. [Beilstein 6 IV 5866.]
