General Description

4-Hydroxypyridine-1-oxide, also known as 4-Hydroxy-1-pyridinol oxide, is a chemical compound with the molecular formula of C5H5NO2. It is a related derivative of pyridine, which is a common compound in biological systems and is found in DNA, RNA, and vitamins. This particular chemical, 4-hydroxypyridine-1-oxide, is characterized by the presence of a hydroxyl group on the fourth carbon of the pyridine ring and an oxide group on the nitrogen atom. Due to these functional groups, it possesses different properties and reactivity compared to the parent compound, pyridine. Details regarding its specific uses, toxicity, and handling precautions are not widely available, suggesting that it may not be extensively used or it may likely be used in specialized contexts such as research.

THE MOLECULAR COMPLEX OF 4-(N-PYRIDINIUM)PYRIDINE-N-OXIDE CHLORIDE WITH TETRACYANOETHYLENE IN THE SYNTHESIS OF SUBSTITUTED PYRIDINE N-OXIDES

The structure of the complex of 4-(N-pyridinium)pyridine-N-oxide chloride with tetracyanoethylene was studied by 13C NMR spectroscopy.The results of the investigation, suggesting the use of this complex in the synthesis of substituted pyridine derivatives, were confirmed experimentally by its reaction with oxygen and with nitrogen-containing nucleophiles.
