Isobutyl nitrite, C4H9NO2, is an alkyl nitrite, an ester of isobutanol and nitrous acid. Its chemical structure is (CH3)2CH-CH2-O-NO.

Isobutyl nitrite is a pungent colorless liquid. It acts as a vasodilator, and is used as an inhalant recreational drug.

[edit] Applications

Amyl nitrite is employed medically to treat heart diseases such as angina and to treat cyanide poisoning.[1] It is also used as an inhalant drug that induces a brief euphoria; whilst already intoxicated with stimulant drugs such as cocaine or ecstasy (see MDMA) the euphoric state intensifies and lasts for several minutes longer. Once some stimulative drugs wear off, a common side effect is a period of depression or anxiety, colloquially called a "come down"; amyl nitrite is sometimes used to "come up" again in order to stop the user from feeling lousy. See Poppers.
