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

Preparation

pyridine is reluctant to undergo electrophilic nitration, pyridine-N-oxide is activated to electrophilic attack and nitration gives 4-nitropyridine-N-oxidel.1124-33-0 synthesis

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
