The most extensively studied 2-pyridone degrader is the gram positive bacterium Arthrobacter crystallopoietes, [25] a member of the phylum Actinomycetota which includes numerous related organisms that have been shown to degrade pyridine or one or more alkyl-, carboxyl-, or hydroxyl-substituted pyridines. 2-Pyridone degradation is commonly ...
4-Pyridone These can adopt three tautomers , a oxo form, a zwitterion form, and a enol form. Whereas 2-pyridone (α) and 4-pyridone (γ) predominantly adopt the oxo form, the 3-pyridone (β) cannot, and instead adopts an equilibrium of the zwitterion form, pyridin-1-ium-3-olate, and the enol form, 3-hydroxypyridine (the canonical form).

Pyridine N-oxide is five orders of magnitude less basic than pyridine: the pK a of protonated pyridine-N-oxide is 0.8. [7] Protonated derivatives are isolable, e.g., [C 5 H 5 NOH]Cl. [3]
The molecular formula C 7 H 8 N 2 O 2 may refer to: N 1-Methyl-2-pyridone-5-carboxamide; N 1-Methyl-4-pyridone-3-carboxamide
2-Aminopyridine is an organic compound with the formula H 2 NC 5 H 4 N. It is one of three isomeric aminopyridines. It is a colourless solid that is used in the production of the drugs piroxicam, sulfapyridine, tenoxicam, and tripelennamine. It is produced by the reaction of sodium amide with pyridine, the Chichibabin reaction. [3]
Mineral salts pyridine broth is a selective medium for bacteria that can metabolize pyridine (which is an unusual carbon source that a select few types of bacteria can use). ). This medium is used to isolate bacteria belonging to the genus Arthrobacter among other bacteria g
The reaction is then completed either by the reformation of the carbonyl through an 1,2-rearrangement or by the formation of the epoxide. There are two possible carbonyl products: one formed by migration of R 1 (4) and the other by migration of R 2 (5). The relative yield of each possible carbonyl is determined by the migratory preferences of ...
