Guaiacol, along with 2,4,6-trichloroanisole, is responsible for cork taint in wine. A method has been developed for extraction and quantitation of the two compounds. noun Pharmacology. a slightly yellowish, aromatic, crystalline substance, C7H8O2, resembling creosote and usually obtained from guaiacum resin: used in medicine chiefly as an expectorant and local anesthetic. Guaiacol is a precursor of vanillin and santalidol (a synthetic sandal- wood fragrance). it is obtained from wood tar by the destructive distillation of hardwood, by the distillation of the phenol fraction of coal tar, or through the use of o-dichlorobenzene. it is processed to yield vanillin.

guaiacol - Swedish translation – Linguee

The present invention is process of synthesizing guaiacol with catechol and dimethyl carbonate as materials. The process includes the steps of heating catechol and phase transfer catalyst to 100-150 deg.c to reach smelting state, adding quantitative alkaline catalyst, heating the mixture to 110-190 deg.c, dropping dimethyl carbonate quantitatively in the molar ratio to catechol of 1.0-2.0 to 1 Figure 5.5 Schematic illustrations of (a) the most stable guaiacol configurations adsorbed on platinum slabs (b - d) other guaiacol configurations adsorbed on platinum slabs; (e) the most stable partially hydrogenated intermediate adsorbed on platinum slabs; (f) … guaiacol, the only non-carcinogenic substrate reported so far [18]. The global reaction catalyzed by POD in the pres-ence of guaiacol is shown in Scheme 1.

Packaging 1 kg in glass bottle 5, 10 kg in poly drum Biochem/physiol Actions Guaiacol, along with 2,4,6-trichloroanisole, is responsible for cork taint in wine. Guaiacol has an ability to inhibit prostaglandin biosynthesis, without causing damage to the gastrointestinal system, unlike classic NSAID (nonsteroidal anti-inflammatory drugs). Guaiacol, along with 2,4,6-trichloroanisole, is responsible for cork taint in wine. A method has been developed for extraction and quantitation of the two compounds.
