4-Phenylpiperidine is a chemical compound. It features a benzene ring bound to a piperidine ring. 4-Phenylpiperidine is the base structure for a variety of opioids , such as pethidine (meperidine), ketobemidone , alvimopan , loperamide , and diphenoxylate .
Pyridine and poly(4-vinyl) pyridine have been shown to form conducting molecular wires with remarkable polyenimine structure on UV irradiation, a process which accounts for at least some of the visible light absorption by aged pyridine samples. These wires have been theoretically predicted to be both highly efficient electron donors and ...
It also maintains List I of chemicals and List II of chemicals, which contain chemicals that are used to manufacture the controlled substances/illicit drugs. The list is designated within the Controlled Substances Act [ 1 ] but can be modified by the U.S. Attorney General as illegal manufacturing practices change.
Piperidine is an organic compound with the molecular formula (CH 2) 5 NH. This heterocyclic amine consists of a six-membered ring containing five methylene bridges (–CH 2 –) and one amine bridge (–NH–).
4-Pyrrolidinylpyridine is an organic compound with the formula (CH 2) 4 NC 5 H 4 N. The molecule consists of a pyrrodinyl group ((CH 2) 4 N-) attached via N to the 4-position of pyridine. It is a white solid. The compound has attracted interest because it (pK a = 9.58) is more basic than dimethylaminopyridine (pK a = 9.41). [1] It is a popular ...
