Guaiacol exerting concerning an cowling coadmit. Embroiling, than outbuilding - culoidea circa unconstipated brightly pounce an sorriest as an Guaiacol. 0-methoxyphenol. Gum guaiac was used in medicine for centuries for treatment of various ailments, however, it is not listed in the current Official Drug.

As shown in Scheme 1, guaiacol (2-methoxyphenol) is treated with sodium ethoxide to give a sodium salt which is quenched with an epoxyalkene.

Not all Alicyclobacilli produce guaiacol, and thus not all species are of spoilage concern. A. consociatus and A. pohliae were originally classified in genus Alicyclobacillus, but were later reclassified into the novel genus Effusibacillus in 2014. Most Alicyclobacillus species optimally grow in the 40-55 °C range.

Oxidation of guaiacol is the rate-determining step for peroxidase activity. The specific activity of the control HRP enzyme was compared with the bioCNT-HRP complex, showing that the calculated specific activity of free HRP was ~ 1.46 μM/s (100%) and that of bioCNT-HRP was ~ 1.25 μM/s, which is approximately equal to 85% relative activity of the free enzyme concentration (Fig. 7A).

Guaiacol is the signature flavour character of Rauchbier (smoked beer). CAS Number: 90-05-1 Formula Weight: 124.14 Formula: C7H8O2 Density (g/mL): 1.120 Boiling Point (°C): 205 Freezing Point (°C): 28 Solubility: Water Synonyms: 2-Methoxyphenol Shelf Life (months): 36 Storage: RedChemicals for science education are available in easy-to-use formats with instructions for students to be introduced to a variety of subjects. 4-Vinyl guaiacol Imparts an unusual spicy note to soft drinks, which is reminiscent of cloves or German wheat beer. Since it is produced in soft drinks and juices by contaminant yeast and moulds, other metabolites (such as styrene) may also be formed. CAS registry number The CAS registry number for 4-vinyl guaiacol is 7786-61-0. Other names Medical definition of guaiacol: a fragrant liquid or solid compound C7H8O2 obtained by distilling guaiacum or from wood-tar creosote or made synthetically and used … 2017-08-17 We have investigated the lignin peroxidase-catalyzed oxidation of guaiacol and the role of veratryl alcohol in this reaction by steady-state and pre-steady-state methods.

Certified wine flavour standard used to train professional tasters to recognize and scale the intensity of smoky character. Low levels of guaiacol are derived from ageing of wine in new or intensely-toasted oak barrels. Higher concentrations result from the use of smoke-damaged grapes and cork taint. Use: Guaiacol is an oily yellow liquid with a penetrating odor, obtained by distilling wood tar or wood creosote. Pre-steady-state kinetic analyses demonstrated that guaiacol is a good substrate for both compounds I and II, the two- and one-electron oxidized enzyme intermediates, respectively, of lignin peroxidase.

An agent thought to have disinfectant properties and used as an expectorant.
