Product Usage
Used as analytical reagent;
For medicine, dyes and spices intermediates;
GB 2760-96 provides for the temporary use of flavors. Mainly used for the preparation of coffee, vanilla, tobacco and tobacco and other flavor. ; In medicine for the manufacture of guaiacol sulfonate, used in the perfumery industry to manufacture vanillin and artificial musk.

Guaiacol Application:

Guaiacol is a precursor to various flavorants, such as eugenol and vanillin.Its derivatives are used medicinally as an expectorant, antiseptic, and local anesthetic. It also can be used as an indicator in chemical reactions that produce oxygen. When oxygen binds to it, the complex turns yellowish brown and absorbs light maximally at about 470 nm

History 

Guajacol was first produced by Otto Unverdorben in 1826 by distillation of guaiacum resin. 


Occurrence 

Guajacol is found in wood tarry red and in wood tars, the largest content is beech wood, as well as in the guaiac resin. Guaiacol is among other phenols formed by thermal or microbial degradation of lignin or phenolic acids (eg, ferulic acid) and is therefore found in many foods, especially in smoked products. Guajacol is one of the flavorings of whiskey, and it may be responsible for the cork in the wine. 


Properties

Guajacol smells smoky-medicinal and tastes sweet. The aroma wave in water is 3 ppb. With its strong hints of smoke Guajacol contributes significantly to the coffee aroma and flavor of smoked foods. The vapor pressure function results according to Antoine according to ln (P) = A- (B / (T + C)) (P in kPa, T in K) with A = 13.6745, B = 3378.850 and C = -104.630 im Temperature range from 373 to 463 K. [12] The enthalpy of evaporation at the boiling point is 52.7 kJ · mol-1. 


With iron (III) ions (ferric chloride) a green color is observed.


The methoxy group has little influence on the acidity of the phenolic OH group, the pKs value has only a very small difference to the phenol.

Use 

Guajacol is used in the fragrance industry for the production of vanillin and eugenol. In the pharmaceutical industry, it is used, for example, in medicaments as expectorant in bronchial diseases (guaifenesin). In coating technology, it is used for the "anti-skinning" properties of inks and varnishes.
