Applications

Suitable for nucleic acids, peptide synthesisN, N-Dimethylformamide is commonly used as a solvent. It is used as a reagent in Bouveault aldehyde synthesis and also in Vilsmeier-Haack reaction. It acts as a catalyst in the synthesis of acyl chlorides. It is used for separating and refining crude from olefin gas. DMF along with methylene chloride acts as a remover of varnish or lacquers. It is also used in the manufacture of adhesives, fibers and films.

Notes

Contains amine and water scavenging sieve.Reaction with sodium hydride gives exothermic decomposition at low temperatures. Keep container tightly closed in a dry and well-ventilated place.
