ethyl nitrite
C2Technical (Chemistry, Pharmacology)
Definition
Meaning
A simple aliphatic ester of nitrous acid and ethyl alcohol, a volatile, flammable liquid with a characteristic sweet odour.
In historical medicine, a volatile drug used as a vasodilator and a remedy for angina pectoris and cyanide poisoning. In modern chemistry, a reagent and synthetic intermediate, also known as nitrous ether.
Linguistics
Semantic Notes
The term primarily denotes a specific chemical compound (C2H5ONO). Its use outside of chemistry/pharmacology is extremely rare. The historical medical sense is now obsolete.

Learning
Memory Aids
Mnemonic
Link 'ethyl' to 'ethanol' (drinking alcohol) and 'nitrite' to 'nitrogen'. Think: 'The nitrogen ester of drinking alcohol'.
Conceptual Metaphor
Not applicable; a literal, technical term.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'нитрат' (nitrate). The correct translation is 'нитрит этила' or 'азотистоэтиловый эфир'.
- The historical preparation 'sweet spirit of nitre' may be translated as 'азотистоэфирный спирт'.
Common Mistakes
- Mispronouncing 'ethyl' as /eˈθaɪl/ or 'nitrite' as /ˈnɪtriːt/.
- Confusing it with 'ethyl nitrate' (a different compound).
- Using it in non-technical contexts.

Frequently Asked Questions
Yes. It is highly flammable, volatile, and toxic if inhaled in significant quantities, causing methemoglobinemia.
No, its medical use is entirely historical. It has been replaced by safer and more effective vasodilators like glyceryl trinitrate (nitroglycerin).
Ethyl nitrite (C2H5ONO) contains the nitrite ion (NO2-). Ethyl nitrate (C2H5ONO2) contains the nitrate ion (NO3-). They are different compounds with distinct chemical properties.
