Bouveault aldehyde synthesis / Vilsmeier-Haack reaction), and is useful in the method of forming aldehydesDMF makes most plastics swell, making it very suitable for solid phase peptide synthesis. It is also used as a component of paint strippers dur to this attributeDMF is very effective at separating and suspending carbon nanotubes, and is recommended by the NIST for use in near infrared spectroscopy of suchDMF is used to recover olefins (eg. 1, 3- Butadiene via extractive distillation)It is an important raw material used in the manufacture of solvent dyes as it gets consumed during the processAs pure acetylene gas cannot be compressed and stored due to the danger of explosion, it is therefore dissolved in Dimethylformamide and stored in appropriate containers url:http://www.dyrichchem.com
