Cinnamyl bromide ( CAS#4392-24-9 )

Listing ID #5534284

Storage method : Recommended storage conditions are 2-8 ℃, and the control temperature should not exceed 60 ℃

Usage : It is a pharmaceutical intermediate. It is some chemical raw materials or chemical products used in the pharmaceutical synthesis process.

Production method: Cinnamyl alcohol is obtained by bromination.Put cinnamyl alcohol, pyridine, and gasoline in a dry reaction pot.Add phosphorus tribromide after stirring and keep the reaction temperature at 20℃ or so.Add it and heat it to 60-70℃ for 2h.Cool to below 30℃, add appropriate amount of ice water, divide to layer.The gasoline layer was washed once with water and 5% sodium bicarbonate solution, and then washed to neutral. The solvent gasoline and pyridine were removed, that is, cinnamyl bromide, with a yield of 95.3%.
