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ChEBI: A member of the class of hydroquinones that is hydroquinone in which one of the benzene hydrogens has been replaced by a methyl group.
Synthesis Reference(s)
Tetrahedron, 44, p. 1227, 1988 DOI: 10.1016/S0040-4020(01)85902-0
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.]
