The chemical compound ethyl nitrite is an alkyl nitrite with a chemical formula C2H5NO2. It may be prepared from ethanol.[2]
Uses
It is used as a reagent with butanone to yield the dimethylglyoxime end product.
Ethyl nitrite is the main ingredient in a traditional ethanol-based South African remedy for colds and flu known as Witdulsies, which is sold in pharmacies. It is known as a traditional Afrikaans remedy; the same remedy is apparently made by the Amish in the US. However, FDA has blocked over-the-counter sales of this same remedy, known in the US as sweet nitrite or sweet spirit of nitre, since 1980.[3] Its use has been associated with fatal methemoglobinemia.[4]
Methemoglobinemia is the primary toxic effect of ethyl nitrite.[5] Due to ethyl nitrite's high volatility and faint smell, in the presence of ethyl nitrite vapors, it is easy to breath a high dose of it without realizing, resulting in methemoglobinemia,[6] which may or may not be severe, or even fatal.
