Hexamethyldisiloxane Manufacturer introduces what HMDSO is:
HMDSO is used as an internal standard to calibrate chemical shifts in H NMR spectra. Its volatility is lower than the standard tetramethylsilane, but it still shows the only singlet near 0 ppm, so it is easier to operate.

The solvating power of HMDSO is even worse than that of alkanes. Therefore, it is sometimes used to crystallize highly lipophilic compounds.

It is used in liquid bandages (sprayed on plasters), such as caviar sprays, to protect damaged skin from other body fluids. It can also be used to soften and remove adhesive residues left by medical tapes and bandages without causing further skin irritation.

The above content is organized and shared by Alkyl Modified Siloxane manufacturer, hoping to help those in need.
