tertButylnitrit
tert-Butyl nitrite is an organic nitrite with the formula (CH3)3C-ONO, commonly written as C4H9NO2. It is the tert-butyl ester of nitrous acid. The compound is a colorless to pale yellow volatile liquid at room temperature and has a characteristic fruity odor. As a nitrite ester, it acts as a nitrosating reagent in organic synthesis and can serve as a source of nitric oxide in biological contexts. It has historically been used as a vasodilator in inhalant mixtures, though such use raises safety concerns and is regulated in many jurisdictions; non-medical use is discouraged.
Preparation and handling: tert-Butyl nitrite is typically prepared by nitrosation of tert-butanol with nitrous acid generated
Safety: Inhalation can cause dizziness, headaches, and methemoglobinemia; skin and eye exposure can be irritating. It
