Hello,Thank you kindly for your reply to our buyer post.In our internet posting, the CAS number was incorrect.Does your company produce pharmaceutical products?The actual product we are looking for is:3-Heptanone, 4,4-diphenyl-6-(1-piperidinyl)- hydrochloride.And the correct CAS No:856-87-1Please let us know about the cost of 1 kg, 2 kg, 5 kg, if possible, and samples of 10 grams or 25 grams.We can forsee now that once we choose a supplier, with the best quality chemicals and the best price, we will purchase up to 5 kg, each MONTH.Please let us know about the possibility of samples and the cost.Sincerely,Robert HoytEvergreen ImportsTEL: (001) 541-603-0768evergreen_imports@yahoo.com
