N,N-Dimethylacetamide can cause cancer according to California Labor Code. It can cause developmental toxicity and male reproductive toxicity according to an independent committee of scientific and health experts. Dimethylacetamide appears as a clear colorless liquid with a faint odor similar to ammonia. About the same density as water.

In this investigation, we explore the kinetics of the hindered rotation about the C—N bond in N,N-dimethylacetamide (DMA). If DMA were a completely rigid molecule, it is expected that the amino methyl protons will exhibit two resonances integrating for three each in the proton NMR, corresponding to CH 3 groups that are "cis" and "trans" to ...

In this investigation, we will examine the barrier of isomerization in N,N-dimethylacetamide (DMA) and some of its derivatives both experimentally (temperature dependent NMR) and computationally (with the WebMO interface to Gaussian 03).

N,N-Dimethylacetamide (DMA) is a planar molecular having a large rotational barrier about the amide bond. Because of its similarity to peptide bonding geometry, DMA is often used to model peptide rotational barriers to examine conformational changes which are energetically feasible.
