Produktbeschreibung:

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.

Guaiacol is a precursor to various flavorants, such as eugenol and vanillin.An estimated 85% of the worlds supply of vanillin comes from guaiacol. The route entails condensation of glyoxylic acid with guaiacol to give mandelic acid, which is oxidized to produce a phenylglyoxylic acid. This acid undergoes a decarboxylation to afford vanillin.

Produktanwendungen:

1. Natural Guaiacol is also use as perfume and antioxidants in food and daily chemicals synthesize vanillin and pharmaceutical intermediates.
2. Used medicinally as an expectorant.
3. Used, because of its anti-oxidant properties, as an anti-skinning agent for paints. Luft & Water Reactions Sensitive to air and light (darkens).
