Allyl alcohol
Last updated: 01/09/2023
(Also known as: allylic alcohol; 3-hydroxypropene; vinyl carbinol)
SUMMARY
Allyl alcohol is a herbicide that is not generally approved for use in the developed world. It is highly toxic to mammals and is a known skin, eye and inhalation irritant. It is miscible with water and many organic solvents and is semi-volatile. It is not thought to be persistent in soil. There is little published data for allyl alcohol related to ecotoxicology.
