General description

Silicone oil is a highly viscous oil[1] made up of poly(dimethylsiloxane-co-methylphenylsiloxane) chains.[2]

Application

Silicone oil has been used as a medium component in containerless protein crystallization techniques which do not require contact with a solid surface.[3] It was used as an oil bath during the synthesis of methyl 2-methylazulene-1-carboxylate.[4]
