General description
Hexamethyldisilazane (HDMS) is an organoslicon compound. HDMS is a colorless liquid used as a reagent and precursor in organic synthesis and organometallic chemistry. It is also used as a sol-gel precursor to fabricate thin films for semiconductor devices.
Application
Hexamethyldisilazane can be used:
- As a precursor to fabricate multilayer quantum dot light-emitting diodes.
- To modify dielectric surfaces of organic thin film transistors.
- To fabricate superhydrophobic coatings on epoxy resins.
- For the silylation of alcohols and phenols.

Alpha-amino acids were pyrolysed at 600 degrees C in the presence of hexamethyldisilazane (HMDS) and the formed volatile products were analysed on line by gas chromatography-mass spectrometry (GC-MS). Glycine, alanine, valine, leucine, isoleucine, norleucine, methionine, phenylalanine yielded principally the trimethylsilyl

Three different drying methods, critical-point drying (CPD), Peldri II, and hexamethyldisilazane (HMDS), were compared using representative animal (rat kidney, trachea, duodenum, lung, and red blood cells) and plant (leaves from ten species of monocotyledons and dicotyledons) specimens. All three drying
