| | N-Acetyl-4-piperidone Usage And Synthesis |
| Chemical Properties | clear orange oily liquid | | Uses | 1-Acetyl-4-piperidone is used as an intermediate in the manufacture of chemicals and pharmaceutical drugs, and manufacture of fentanyl. | | Purification Methods | Purify it by fractional distillaton through a short Vigreux column (15mm, p 11). The 2,4-dinitrophenylhydrazone has m 212-213o (from EtOH). It is freely soluble in H2O but insoluble in Et2O. [McElvain & McMahon J Am Chem Soc 71 901 1949, Beilstein 21/6 V 246.] |
