Description

Dimethylacetamide (DMA) 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 synthesis. DMA is miscible with most other solvents, although it is poorly soluble in aliphatic hydrocarbons.
