What does DMA stand for?
| Full form | N,N-Dimethylacetamide |
|---|---|
| Category | Science & engineering |
| Type | Abbreviation |
The abbreviation DMA stands for N,N-dimethylacetamide in chemical records. NIST lists DMA and DMAc as aliases of this species, whose CAS Registry Number is 127-19-5.
The chemical record identified here is N,N-Dimethylacetamide, CAS 127-19-5. Preserve the N,N- prefix and complete name when identifying this record. DMAc is an alias listed for the same NIST species, rather than a separate chemical just because the spelling differs. Dimethylamine is a different record, CAS 124-40-3, even though DMA can also abbreviate that name. Matching the recorded name and identifier helps read a document; it does not authenticate a container or establish what an unknown sample contains.
Meaning in context
- N,N-Dimethylacetamide
- The complete recorded name; preserve the prefix instead of silently shortening the identity.
- DMA or DMAc
- Aliases listed for this NIST species. DMA is also used elsewhere, so context remains essential.
Practical examples
Read an alias
- Before
DMAc must be a different species from the NIST N,N-dimethylacetamide entry.
- After
NIST lists DMAc and DMA as aliases in the N,N-dimethylacetamide record, CAS 127-19-5.
Alias variation within one record differs from a genuinely different chemical record.
Distinguish two records
- Before
Dimethylamine and dimethylacetamide are the same because both can be called DMA.
- After
The cited records give different full names and identifiers: dimethylamine 124-40-3 and N,N-dimethylacetamide 127-19-5.
The shared abbreviation cannot override the distinct recorded identities.

Use DMA with clarity
Are DMA, DMAc and dimethylamine interchangeable chemical names?
See all guidance
Identify this record
Use the full name and identifier.
N,N-dimethylacetamide, CAS 127-19-5, is the record named here.
Read DMAc
Check the alias in the original record.
DMAc is listed as an alias for this species.
Compare dimethylamine
Keep its different identifier.
Dimethylamine is recorded separately as CAS 124-40-3.
Distinguish two aliases within one chemical record from a different recorded chemical identity.
