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]
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 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.
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 ...
2,2,4-Trimethyl-1,2-dihydroquinoline (usually abbreviated TMQ, known historically as Acetone-anil) is an aminic antioxidant commonly used as a stabiliser in rubbers and some plastics. Synthesis [ edit ]
[1] [2] [3] It is also the N,N-dimethylated derivative of 5-methoxy-α-methyltryptamine (5-MeO-αMT or α,O-DMS) and the N-methylated derivative of 5-methoxy-α,N-dimethyltryptamine (5-MeO-α,N-DMT or α,N,O-TMS). [1] [2] [3] The compound was described by Alexander Shulgin in TiHKAL as a putative psychedelic drug, but does not appear to have ...
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.
Quazepam, sold under the brand name Doral among others, is a relatively long-acting benzodiazepine derivative drug developed by the Schering Corporation in the 1970s. [2] Quazepam is used for the treatment of insomnia , including sleep induction and sleep maintenance. [ 3 ]
