English alias: HMDS; Hexamethyldisilazane; DYNASYLAN HMDS; Bis (trimethylsilyl) amine; 1,1,1- Trimethyl-N- (trimethylsilyl) silanamine

Hexamethyldisilazane is  a kind of chemical with features of colorless and transparent liquid. It can be easily hydrolyzed,and then emit NH3 and generate hexamethyldisiloxane. In the presence of a catalyst, an alcohol or a phenol is reacted to form a trimethylalkoxysilane or a trimethylallyloxy silane. With the reaction of anhydrous hydrogen chloride,it can emit NH3 or NH4Cl and then generate trimethylchlorosilane.It can be made by the reaction of trimethylchlorosilane and NH3. It can also be used as assistant of silicon carbide fiber to improve the heat resistance and strength of silicon carbide fiber and can also be used as coating agent for hydrophobic agent of fumed silica surface and reagent for providing N atom in organic synthesis reaction.It is used to prepare organosilicon compounds as well.
