Chemical Properties: Guaiacol has a characteristic sweet odor. It is slightly phenolic.
Chemical Properties: Light Yellow Oil
Uses: Guaiacol is a precursor of vanillin and santalidol (a synthetic sandal- wood fragrance). it is obtained from wood tar by the destructive distillation of hardwood, by the distillation of the phenol fraction of coal tar, or through the use of o-dichlorobenzene. it is processed to yield vanillin.
Uses: Synthetic flavors, medicine (expectorant).
Uses: A phenolic natural product and reducing co-substrate for COX reactions.
Definition: A monomethoxybenzene that consists of phenol with a methoxy substituent at the ortho position.
