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.

2-Methoxyphenol Guaiacol production did not occur in the absence of either a precursor or A. acidoterrestris FB2 and guaiacol was not produced by A. acidoterrestris FB2 in the samples supplemented with ferulic acid. The presence of Alicyclobacillus spp. that has the ability to produce guaiacol, as well as the substrates vanillin or vanillic acid is prerequisite for production of guaiacol. Guaiacol is produced when the lignin found in wood is burned, and it’s partly responsible for the flavour of smoke-preserved food such as bacon and fish, as well as peated whisky and roast coffee.

Guaiacol is also present in wood smoke, as a product of pyrolysis of lignin. Guaiacol has been found in the urine of patients with neuroblastoma and pheochromocytoma. As shown in Scheme 1, guaiacol (2-methoxyphenol) is treated with sodium ethoxide to give a sodium salt which is quenched with an epoxyalkene. The final step involves the oxidation of the alkene to the diol using potassium permanganate [4 ].

Abstract. Oxidation of guaiacol by peroxidases in the presence of H2O2 is the basis for a widely used colorimetric assay. However, the nature of the assay product, which has an absorption maximum around 470 nm, had not been determined. In the present study, we combined HPLC with a rapid scanning uv-visible detector and observed a single product

(chemistry) A naturally occurring aromatic organic compound with the chemical formula C 6 H 4 (OH)(OCH 3 ), having certain medicinal applications. The enzyme activity was measured using guaiacol as a chromogenic depolymerization processes yield guaiacol as the main low molecular weight product.

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
