Guaiacol Chemical Properties,Usage,Production

Chemical Properties
Light Yellow Oil
A phenolic natural product and reducing co-substrate for COX reactions.
ChEBI: A monomethoxybenzene that consists of phenol with a methoxy substituent at the ortho position.
General Description
Colorless to amber crystals or liquid. Density (of solid) 1.129 g / cm3. Solidifies at 28°C (82.4°F), but may remain liquid for a long time even at a much lower temperature. Slightly water soluble . Soluble in aqueous sodium hydroxide. Used medicinally as an expectorant. Used, because of its anti-oxidant properties, as an anti-skinning agent for paints.
Air & Water Reactions
Sensitive to air and light (darkens). Slightly water soluble.
Reactivity Profile
Guaiacol may react with oxidizing materials. Guaiacol forms salts readily with bases.
Fire Hazard
Guaiacol is combustible.
