Examples
By CEFR Level
- 'Nitrous ether' is an old medicine.
- In the 1800s, some doctors used nitrous ether to treat chest pain.
- The historical formulary listed 'Sweet Spirit of Nitrous Ether' as a remedy for angina, though its efficacy and safety were questionable.
Learning
Memory Aids
Mnemonic
Think 'NITRous' for the nitrogen-containing nitrite group, and 'ETHER' for the volatile, ether-like liquid. 'Nitrous' is related to 'nitrite', not the more common 'nitrous oxide' (laughing gas), though both have historical recreational use.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'азотный эфир' which is vague. The precise Russian equivalent is 'нитрит этила' (ethyl nitrite) or historically 'азотный эфир' or 'сладкий спирт азотистой кислоты'. Confusion with 'эфир' (diethyl ether) is common.
Common Mistakes
- Confusing it with 'nitrous oxide' (N₂O, laughing gas).
- Using 'ether' alone to mean this substance.
- Assuming it is a current, standard medicinal product.

FAQ
Frequently Asked Questions
No. Nitrous ether is ethyl nitrite (C₂H₅NO₂), a liquid. Laughing gas is nitrous oxide (N₂O), a gas. Both have historical use as inhalants for euphoric effects, but they are different chemicals.
No. Its medicinal use is entirely historical. Modern medicine has safer and more effective vasodilators and antispasmodics.
This is an archaic synonym for a solution of nitrous ether (ethyl nitrite) in alcohol, commonly listed in old pharmacopoeias.
Because the substance itself is obsolete in practice, replaced by better-understood and safer compounds. The term survives only in historical analysis.
