Anwendungen

Propargyl chloride may be used as propargylating agent in the preparation of arabinogalactan propargyl ethers with degree of substitution up to 1.8. It may be used for the in situ preparation of propargyltrichlorosilane and allenyltrichlorosilane, required for the synthesis of optically active allenic and homopropargylic alcohols. Propargyl chloride solution may be used for the enantioselective synthesis of enantiomerically enriched homopropargyl alcohols.

Bemerkungen

Store in cool. Keep container tightly closed in a dry and well-ventilated place. Store away from oxidizing agent.
