  2. N-Methylacetamide - Wikipedia

    en.wikipedia.org/wiki/N-Methylacetamide

    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]

  3. Zwitterion - Wikipedia

    en.wikipedia.org/wiki/Zwitterion

    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 ...

  4. Foreign body reaction - Wikipedia

    en.wikipedia.org/wiki/Foreign_body_reaction

    Zwitterionic polymers have the ability to reduce nonspecific adsorption of proteins and cells at biological interfaces. Zwitterionic coatings are often used to minimize the negative effects of foreign body response for implanted devices and improve the device's biocompatibility.

  5. Acetamide - Wikipedia

    en.wikipedia.org/wiki/Acetamide

    Acetamide (systematic name: ethanamide) is an organic compound with the formula CH 3 CONH 2. It is an amide derived from ammonia and acetic acid. It finds some use as a plasticizer and as an industrial solvent. [5] The related compound N,N-dimethylacetamide (DMA) is more widely used, but it is not

  6. Amide - Wikipedia

    en.wikipedia.org/wiki/Amide

    Structure of acetamide hydrogen-bonded dimer from X-ray crystallography. Selected distances: C-O: 1.243, C-N, 1.325, N---O, 2.925 Å. Color code: red = O, blue = N, gray = C, white = H. [8] The lone pair of electrons on the nitrogen atom is delocalized into the Carbonyl group, thus forming a partial double bond between nitrogen and carbon.

  7. Dimethylacetamide - Wikipedia

    en.wikipedia.org/wiki/Dimethylacetamide

    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 ...

  8. N,N'-Methylenebisacrylamide - Wikipedia

    en.wikipedia.org/wiki/N,N'-Methylenebisacrylamide

    N,N′-Methylenebisacrylamide (MBAm or MBAA, colloquially "bis") is the organic compound with the formula CH 2 [NHC(O)CH=CH 2] 2. A colorless solid, this compound is a crosslinking agent in polyacrylamides , e.g., as used for SDS-PAGE .

  9. Polysulfobetaine - Wikipedia

    en.wikipedia.org/wiki/Polysulfobetaine

    Polysulfobetaines are zwitterionic polymers that contain a positively charged quaternary ammonium and a negatively charged sulfonate group within one constitutional repeat unit. [1] [2] In recent years, polysulfobetaines have received increasing attention owing to their good biotolerance and ultralow-fouling behavior towards surfaces. These ...
