ethamine
Very Low (Technical Only)Highly Technical/Scientific
Definition
Meaning
A chemical compound belonging to the class of organic amines, specifically ethylamine (C₂H₇N), often used as a base or building block in organic synthesis.
In technical contexts, specifically organic chemistry, any derivative of ethylamine or referring to the simplest aliphatic amine with two carbon atoms. Can also be used more broadly to discuss related compounds in chemical nomenclature or industrial processes.
Linguistics
Semantic Notes
The term is almost exclusively used in specialized scientific literature and industrial chemistry. It is not a common term in general English and may be confused with 'ethylamine' (its systematic name) by non-specialists.

Learning
Memory Aids
Mnemonic
Think: 'ETHyl' + 'AMINE' = ETHAMINE. It's the amine (NH₂) version of ethane (C₂H₆).
Conceptual Metaphor
A fundamental building block (like a Lego brick) for constructing more complex molecules.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'этанол' (ethanol). 'Ethamine' is 'этиламин' or 'аминоэтан' in Russian.
Common Mistakes
- Misspelling as 'ethymine' or 'ethamin'.
- Confusing it with 'ethane' or 'ethanol'.
- Using it in non-scientific contexts.

FAQ
Frequently Asked Questions
Yes, in standard chemical nomenclature, 'ethamine' is a common name that refers specifically to ethylamine (CH₃CH₂NH₂).
It is extremely unlikely. The term is confined to highly technical scientific and industrial contexts.
No, it is exclusively a noun referring to a specific chemical compound.
Like many simple amines, it is corrosive, flammable, and has a strong, unpleasant ammonia-like odour.
