| Definition | 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. |
