Used as an intermediate in the synthesis of pesticides and biocides due to its reactive chlorine atoms and allylic alcohol structure. Commonly employed in the production of soil fumigants and nematicides. Also serves as a building block in organic synthesis for introducing halogenated allyl groups. Its high reactivity makes it suitable for use in polymer modification and as a crosslinking agent in specialty resins. Handling requires caution due to its toxicity and potential for irritation.
