Aplicaciones

Isopentyl nitrite is used in the conversion of 2,6-disubstituted phenols to diphenoquinones and aminophenols to quinone diazides. It acts as an oxidant and nitrosating agent. It finds application in aromatic arylation, deamination of arylamines using tetrahydrofuran as a hydrogen donor. It is also useful for the preparation of benzyne using anthranilic acid. It is an antihypertensive and vasodilator to treat heart diseases such as angina and an antidote for cyanide poisoning. Further, it is used as a solvent and cleaning agent for a printed circuit board. In addition to this, it is considered to be a replacement for freon.

Notas

Air, moisture and light sensitive. Store in a cool place. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with oxidizing agents and alcohol.
