Erythritol tetranitrate (ETN) is an explosive compound chemically similar to PETN, though it is thought to be slightly more sensitive to friction and impact.

Like many nitrate esters, ETN acts as a vasodilator, and was the active ingredient in Cardilate tablets. Ingestion of or prolonged skin contact with ETN can lead to what is known as a nitro headache.
