Description

Description générale

N,N-Dimethylformamide (DMF) is commonly employed as a solvent for various organic reactions. DMF is a useful solvent employed for the isolation of chlorophyll from plant tissues. It is widely employed reagent in organic synthesis. It plays multiple roles in various reactions such as solvent, dehydrating agent, reducing agent as well as catalyst. It is a multipurpose building block for the synthesis of compounds containing O, -CO, -NMe₂, -CONMe₂, -Me, -CHO as functional groups.

Application

N,N-Dimethylformamide (DMF) may be employed as a solvent in the following studies:

• Extraction of chlorophyll containing pigments from the intact tissues of cotyledons of Cucumis sativus.
• Isolation of chlorophyll a from the cell cultures of unicellular marine algae.4
• As reducing agent and solvent for the preparation of Au@Ag core-shell nanocrystals.
