Abstract Allyl alcohol (CAS # 107-18-6) is a colorless liquid with a pungent, mustard-like odor. It is soluble in water and has a chemical structure of CH2CHCH2OH. It is used as an industrial solvent, herbicide, and fungicide and as raw material in manufacturing of various polymers, pharmaceuticals, pesticides, and other allyl compounds. Preclinical acute toxicity studies have shown that allyl alcohol causes skin and eye irritation and kidney and liver damage in animals. The most important adverse effects of occupational exposures to allyl alcohol are upper respiratory tract irritation and burning of the eyes. It is also hazardous to aquatic organisms and plants.
