General description

Silicone oil is a highly viscous oil made up of poly(dimethylsiloxane-co-methylphenylsiloxane) chains.

Application

Silicone oil has been used as a medium component in containerless protein crystallization techniques which do not require contact with a solid surface. It was used as an oil bath during the synthesis of methyl 2-methylazulene-1-carboxylate.
