4-Nitropyridine N-oxide Chemical Properties,Uses,Production

Chemical Properties

white to light yellow crystal


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


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.
