Beschreibung

Allgemeine Beschreibung

Dichloromethane (DCM) is a chlorinated organic solvent with a wide range of industrial applications and organic syntheses. It has a low boiling point, high density and is immiscible in water. DCM is susceptible to degradation with time, which can be suppressed by adding amylene as a stabilizer.
