N-Methylacetamide is a flammable, difficult to ignite, hygroscopic, crystalline, colourless solid with a faint odor that is soluble in water. [1] Several isomeric forms are known. [8] [9] In solution, it is 97–100% present as the Z isomer with a polymeric structure. [10] [4] The compound has a high dielectric constant of 191.3 at 32 °C. [11]
The related compound N,N-dimethylacetamide (DMA) is more widely used, but it is not prepared from acetamide. Acetamide can be considered an intermediate between acetone , which has two methyl (CH 3 ) groups either side of the carbonyl (CO), and urea which has two amide (NH 2 ) groups in those locations.
In chemistry, a zwitterion (/ ˈ t s v ɪ t ə ˌ r aɪ ə n / TSVIT-ə-ry-ən; from German Zwitter 'hermaphrodite'), also called an inner salt or dipolar ion, [1] is a molecule that contains an equal number of positively and negatively charged functional groups. [2] 1,2-dipolar compounds, such as ylides, are sometimes excluded from the ...
The chemical reactions of dimethylacetamide are typical of N,N-disubstituted amides. Hydrolysis of the acyl-N bond occurs in the presence of acids: CH 3 CON(CH 3) 2 + H 2 O + HCl → CH 3 COOH + (CH 3) 2 NH 2 + Cl −. However, it is resistant to bases. For this reason DMA is a useful solvent for reactions involving strong bases such as sodium ...
4-Acetamidobutanal, also known as N-acetyl-γ-aminobutyraldehyde, N-acetyl-GABAL, or N-acetyl-GABA aldehyde, is a metabolic intermediate in the biosynthesis of γ-aminobutyric acid (GABA) from putrescine.
γ-Glutamylmethylamide (gamma-glutamylmethylamide, abbrev.GMA, synonyms N-methyl-L-glutamine, metheanine) is an amino acid analog of the proteinogenic amino acids L-glutamic acid and L-glutamine, found primarily in plant and fungal species; simply speaking, it is L-glutamine methylated on the amide nitrogen.

N,N-Dimethyl-4-methylthioamphetamine (DMMTA or N,N-dimethyl-4-MTA; code name PAL-1062), also known as 4-methylthio-N,N-dimethylamphetamine (4-MTDMA), is a monoamine releasing agent (MRA) of the amphetamine family related to 4-methylthioamphetamine (4-MTA) and 4-methylthiomethamphetamine (4-MTMA or NMMTA). [1] [2] [3] It has been described as an ...
