      Product Detail  


    Guaiacol is the methyl ether of pyrocatechol. It is a main constituent of creosote obtained from wood tar (mainly beech) by distillation mostly between 203 and 220 C. It is synthesized from anisole also. The dimethyl ether of pyrocatechol is called veratrol. They and their derivatives are used as an external antiseptic, expectorant, gastric sedative, deodorant, and as a parasiticide. Methoxyphenols are used in manufacturing stabilizers and antioxidants for plastics and rubbers. They are also used in analgesics, local anesthetic, flavorings, biocides, antiseptics. 2-Methoxyphenol is used in manufacturing vanillin and other flavorings.

    Widely used in the manufacture of vanillin. Useful intermediate in the pharmaceutical and dye and spices intermediates.

    Description and Applications   


    Uses:

    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


    Description:
    Guaiacol is a naturally occurring organic compound with the formula C6H4(OH)(OCH3), first isolated by Otto Unverdorben in 1826. Although it is biosynthesized by a variety of organisms,this yellowish aromatic oil is usually derived from guaiacum or wood creosote. Samples darken upon exposure to air and light. Guaiacol is present in wood smoke, resulting from the pyrolysis of lignin. The compound contributes to the flavor of many compounds, e.g., roasted coffee.
