hexamethyldisiloxane
Sign in to saveAlso known as HMDSO, ((CH3)3Si)2O, oxybis(trimethylsilane), bis(trimethylsilyl) ether, bis(trimethylsilyl) oxide
Hexamethyldisiloxane (HMDSO or MM) is an organosilicon compound with the formula O[Si(CH3)3]2, often abbreviated O[SiMe3]2. This volatile colourless liquid is used as a solvent and as a reagent in organic synthesis. It is prepared by the hydrolysis of trimethylsilyl chloride. The molecule is the protypical disiloxane and resembles a subunit of polydimethylsiloxane.
