Guaiacol beta-glucoside. 2-Methoxyphenyl-beta-D-glucopyranoside. 6092-24-6. beta-D-Glucopyranoside, 2-methoxyphenyl- 2019-06-12 Guaiacol formed in the decarboxylation reaction is oxidized by peroxidase to tetraguaiacol, a chromophoric substance, which is measurable at 470 nm. Soluble, Guaiacol. Product ID. G3574.
It has a role as an expectorant, a disinfectant, a plant metabolite and an EC 1.1.1.25 (shikimate dehydrogenase) inhibitor. 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 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.
