Packing 200kg / plastic bucket Applications Cinnamyl chloride is used in the enantioselective total synthesis of helioporins C and E, bioactive marine diterpenes. Storage: Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Recommended storage temperature: 2 - 8°C Solution: Cinnamyl chloride can be miscible with alcohol and ether, soluble in acetone, soluble in benzene, insoluble in water. Production method: obtained by chloromethylation of styrene. Hydrochloric acid and formaldehyde were added to the reaction vessel, and styrene was added thereto with stirring, and the mixture was heated under reflux for 3 hours. After standing for 1 h, the lower layer of waste acid was separated, and the upper reaction liquid was dehydrated with anhydrous calcium chloride to obtain cinnamyl chloride.
