Pyridine is a basic heterocyclic organic compound with the chemical formula C 5 H 5 N. It is structurally related to benzene, with one methine group (=CH−) replaced by a nitrogen atom (=N−). It is a highly flammable, weakly alkaline, water-miscible liquid with a distinctive, unpleasant fish
4,4′-Bipyridine (abbreviated to 4,4′-bipy or 4,4′-bpy) is an organic compound with the formula (C 5 H 4 N) 2. It is one of several isomers of bipyridine. It is a colorless solid that is soluble in organic solvents. is mainly used as a precursor to N,N′-dimethyl-4,4′-bipyridinium [(C 5 H 4 NCH 3) 2] 2+, known as paraquat.
4-Benzylpiperidine is a drug and research chemical used in scientific studies. ... [4] Catalytic hydrogenation of the pyridine ring then completes the synthesis. [5]
MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) is an organic compound. It is classified as a tetrahydropyridine . It is of interest as a precursor to the monoaminergic neurotoxin MPP + , which causes permanent symptoms of Parkinson's disease by destroying dopaminergic neurons in the substantia nigra of the brain .
1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine causes permanent symptoms of Parkinson's disease. (–)-Mitragynine is a naturally occurring tetrahydropyridine. 2,3,4,5-Tetrahydropyridine, a colorless liquid, is commercially available. It is an imine. Illustrating another isomer of tetrahydropyridine, 6-acetyl-2,3,4,5-tetrahydropyridine occurs ...
Industrially, piperidine is produced by the hydrogenation of pyridine, usually over a molybdenum disulfide catalyst: [12] C 5 H 5 N + 3 H 2 → C 5 H 10 NH. Pyridine can also be reduced to piperidine via a modified Birch reduction using sodium in ethanol. [13]
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 ...
Picolinic acid is an organic compound with the formula NC 5 H 4 CO 2 H. It is a derivative of pyridine with a carboxylic acid (COOH) substituent at the 2-position. It is an isomer of nicotinic acid and isonicotinic acid, which have the carboxyl side chain at the 3- and 4-positions, respectively. It is a white solid although impure samples can ...
