Hexamethyldisilazane HMDS C6H19NSi2 CAS 999-97-3

    Hexamethyldisilazane, also known as HMDS, is an important organosilicon compound, a colorless and transparent liquid. It is readily hydrolyzed and gives off NH3 to produce hexamethyldisilyl ether. In the presence of a catalyst, it reacts with alcohols or phenols to produce trimethylalkoxysilane or trimethylaroxysilane. Reacts with anhydrous hydrogen chloride, releasing NH3 or NH4Cl, to produce trimethylchlorosilane.     Hexamethyldisilazane mainly used as methyl silane alkylation (such as amikacin, penicillin, cephalosporins and kinds of penicillin derivatives), hydroxyl protectants of antibiotics. It is used as surface treatment agent of diatomite, white carbon black, titanium and blond additives of photoresist in the semiconductor industry. It is used as treatment agent of tearing strength resistance. It is used as a solvent in organic synthesis and organometallic chemistry. It is used as an adhesion promoter for photoresist in photolithography. it i…
