Standard pharmaceuticals such as nitroglycerine and amyl nitrite are precursors to nitric oxide. Amyl nitrite is administered to treat cyanide poisoning. Accidental aspiration of amyl or butyl nitrites may cause lipoid pneumonia. Treatment of the indanone with amyl nitrite in methanol with HCl afforded the hydroxyimino ketone. First responders typically carry a cyanide poison kit containing amyl nitrite. Amyl nitrite may also intensify the experience of synesthesia. Amyl nitrite is a chemical compound with the formula CHONO. The term "amyl nitrite" encompasses several isomers. Mixing it with amyl nitrite, another vasodilator, is particularly dangerous and potentially fatal. They take their name from the Australian slang for amyl nitrite, also known as poppers. Poirot then writes his story, and ceases to take his amyl nitrite heart medicine. Amyl nitrate is the chemical compound with the formula CH(CH)ONO. It is the ester of amyl alcohol and nitric acid. Amyl nitrites were discontinued in 2012 in standard cyanide kits. This molecule consists of the 5-carbon amyl group attached to a nitrate functional group.
