2-Methylhydroquinone Usage And Synthesis
Chemical Propertieswhite solid
UsesAntioxidant, polymerization inhibitor.
UsesMethylhydroquinone is used as stabilizer and antioxidant in aerylic monomers to prevent polymerization.
UsesMethylhydroquinone is a marine fungus metabolite, showing activity as an angiosupressor that interferes with the Akt pathway. Allows for screening of novel inhibitors of angiogenesis.
DefinitionChEBI: A member of the class of hydroquinones that is hydroquinone in which one of the benzene hydrogens has been replaced by a methyl group.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 DescriptionMethylhydroquinone is produced by the oxidation of o-cresol by the mutants G103S, G103S/A107G, and G103S/A107T.
Flammability and ExplosibilityNotclassified
Biochem/physiol ActionsMethylhydroquinone (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 MethodsCrystallise the quinone from EtOH. [Beilstein 6 IV 5866.]
