Beschreibung

General description

Dichloromethane, also known as methylene chloride, is a polar organochlorine compound. It is a colorless, volatile, and high-density liquid that is miscible with many organic solvents. As a result, it is widely used as a solvent in products such as polymers, adhesives and paints.

Application

Dichloromethane is used as

• A solvent to prepare mobile phase in Liquid chromatography.
• Extraction solvent in the decaffeination of coffee and as a paint stripper.
• Solvent lipid extraction to determine the lipid classes and fatty acids in samples.
• An elution solvent in flash chromatography.

OmniSolv^® HR-GC

Stabilized with an alkene.
