1-Benzyl-4-piperidone, also called N-benzyl-4-piperidone, is a derivative of 4-piperidone.
Physical properties
1-Benzyl-4-piperidone is normally in liquid state with a yellow color.[2] It also has a strong odor. Additionally, 1-benzyl-4-piperidone has a solubility of 12 g/L in water at room temperature.[3]
Pharmaceutical chemistry usage
Like the related compound 4-piperidone, 1-benzyl-4-piperidone can be used in the synthesis of fentanyl. While using 1-benzyl-4-piperidone as the starting precursor initially yields benzylfentanyl (which is considered as virtually inactive), the resulting compound can be converted to fentanyl, according to Paul Jassen's works.[4][5]
Regulations
As other drug precursors, 1-benzyl-4-piperidone is heavily regulated like its parent chemical. It is for example a compound on the DEA list[6] and a Class A precursor under Canada's CDSA law.[7]
