Application

N,N-Dimethylformamide-d7 may be used to analyze the degree of acrylation by proton NMR during the preparation of polyethylene glycol diacrylate (PEG-DA) from poly(ethylene glycol) (PEG).

General description

N,N-Dimethylformamide-d7 (DMF-d7) is a deuterated NMR solvent containing 0.03% (v/v) TMS (tetramethylsilane). It is useful in NMR-based research and analyses. Pulsed neutron diffraction measurements of different concentrations of molar lithium chloride (LiCl) solutions in DMF-d7 have been carried out to investigate the chloride ion solvation.

Cationic naked nanocrystals (NCs) are useful building units for assembling hierarchical mesostructured materials. Until now, their preparation required strongly electrophilic reagents that irreversibly sever bonds between native organic ligands and the NC surface.
