Description

Hexamethyldisiloxane is used as a solvent in organic reactions. It finds application as an international standard for 1H 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. It is also used to make low-k dielectric materials for the semi-conductor industries by plasma-enhanced chemical vapor deposition(PECVD) method.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
