General description

Dichloromethane (DCM) is a chlorinated organic solvent with a wide range of industrial applications. It has low boiling point, high density and is immiscible in water. Degradation of DCM by various methods has been reported. Ultrasonic absorption studies of liquid DCM shows strong relaxation effect. A study reports the dielectric characteristics of DCM over a wide frequency range. DCM is susceptible to degradation with time, which can be suppressed by adding amylene as a stabilizer.

Application

Dichloromethane has been used during the Boc-deprotection of immobilized Boc-NH2-poly(ethylene glycol)-plasma layers.
