I am interested in purchasing dextromethorphan HBr as a starting material for chemical synthesis of tetrahydroisoquinolines. This would be a single purchase now, but I may wish to buy more dextromethorphan HBr in the future if my research is successful. Do you want to sell 100 or 200 gram amount of dextromethorphan HBr for this purpose? What is your price? I hope this buying and selling can be good for both of us.SincerelyCountry:USA
