| 4-Nitropyridine N-oxide Usage And Synthesis |
| Preparation | pyridine is reluctant to undergo electrophilic nitration, pyridine-N-oxide is activated to electrophilic attack and nitration gives 4-nitropyridine-N-oxidel. |
| Chemical Properties | white to light yellow crystal |
| Uses | 4-Nitropyridine N-oxide may be used in the preparation of several 4-substituted pyridine-N-oxides and pyridines. |
| Uses | The N-oxide derivative of a nitrated pyridine that has been shown to inhibit Na,K-ATPase activity. 4-Nitropyridine N-Oxide is a quorum sensing inhibitor. |
| General Description | Solid. |
| Air & Water Reactions | May be deliquescent. |
| Reactivity Profile | Aromatic nitro compounds range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction. |
| Health Hazard | High toxicity via oral exposure. |
| Fire Hazard | When heated to decomposition, 4-Nitropyridine N-oxide emits very toxic fumes of nitrogen oxides. Avoid decomposing heat. |
| Safety Profile | Poison by ingestion and skincontact. Questionable carcinogen with experimentaltumorigenic data. Mutation data reported. Mixtures withdiethyl-1,4-dihydro-2,6-dimethylpyridine-3,5-dicarboxylateexplode when heated above 130°C. When heated todecompositio |
