Anwendungen

Hexamethyldisiloxane is used as a solvent in organic reactions. It finds application as an international standard for <sup>1</sup>H NMR spectroscopy for calibrating chemical shift. Further, it is used in liquid bandages to protect skin from irritation. In addition, it is used to measure tissue oxygen tension as a receptor molecule.

Bemerkungen

Hygroscopic. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents, acids, bases and oxygen.
