General description
Dimethylamine is utilized as a building block or reagent in the production of polyurethanes, ion-exchange resins, and dyes.
Application
Dimethylamine (DMA) solution can be used:
- To synthesize Ge7O14.5F2‚[(CH3)2NH2]3(H2O)0.86, a germanate-based porous inclusion complex.
- To synthesize ethyl 2-dimethylamino-4,6-diarylpyrimidine-5-carboxylates.
- To convert 5′-bromo-2,2′-bithiophene-5carboxaldehyde to 5′-dimethylamino-2,2′-bithiophene-5-carboxaldehyde.
