N,N-Dimethylformamide Molecular Biology Reagent

Product No. D4551

Synonym: DMF

Product Description

DMF is a polar organic solvent that is widely used in the synthesis of organic compounds. The high solvent power and stability of DMF at elevated temperatures contribute to its utility. DMF is a solvent for vinyl resins, acetylene, butadiene, and polyacrylic fibers. It is also a catalyst in carboxylation reactions.1,2

DMF is also utilized in chromatographic applications such as HPLC, capillary electrochromatography, and capillary electrophoresis.3,4,5 A capillary electrophoresis study has been published on the mobility of large organic cations in such non-aqueous solvents as DMF.6 DMF has been used for the separation of aliphatic amines in microfabricated capillary electrophoresis devices.7

CNBr-activated diol-silica supports for high performance affinity chromatography have been prepared with DMF.8 DMF has also been used for peptide and protein crystallization.9,10
