Dimethylacetamide is the organic compound with the formula CH₃C(O)N(CH₃)₂. This colorless, water miscible, high boiling liquid is commonly used as a polar solvent in organic chemistry. DMAc is miscible with most other solvents, although it is poorly soluble in aliphatic hydrocarbons.

The chemical reactions of dimethylacetamide are typical of N,N-disubstituted amides. It will hydrolyze in the presence of acids:

CH₃CON(CH₃)₂ + H₂O + HCl → CH₃COOH + (CH₃)₂NH₂⁺Cl^-

Dimethylacetamide is useful as a medium for strong bases such as sodium hydroxide.^[1] Dimethylacetamide is commonly used as a solvent for fibers or in the adhesive industry. It is also employed in the production of pharmaceuticals and plasticizers as a reaction medium.
