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.
