Application:
Hexamethyldisilazane (HMDS) (CAS: 999-97-3), alkaline silanizing protectant, inorganic treatment agent of stuffing. Hexamethyldisilazane is a bulk organo silicon compound, being a quite useful silanizing agent. It is a reagent for the preparation of trimethylsilyl derivatives. HMDS can be used for silanizing the surface of silicon water, cellulose. HMDS can also be used to dehydrate cells of biomaterials for scanning electron microscopy (SEM). The hexamethyldisilazane coatings on various nanoparticles make them be resistant to water contamination and flocculation during synthesis. HMDS can also be used as a modifier to control the shape, formation of agglomerates surface area and pore size of silica particles. HMDS is an adhesion promoter for photoresist in photolithography, and is also useful in the pyrolysis-gas chromatography-mass spectrometry to enhance the detectability of compounds with polar functional groups. 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. Soluble in organic solvents, it will be rapidly hydrolyzed in contact with air to form trimethylsilanol and hexamethyldisilyl ether. Deactivation of chromatographic support materials. 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. HMDS is used as a solvent in organic synthesis and organometallic chemistry. HMDS is used for the preparation of trimethylsilyl ethers from hydroxy compounds. It is used as an alternative to critical point drying during sample preparation in electron microscopy. It is added to analyte to get silylated diagnostic products during pyrolysis in gas chromatography- mass spectrometry.
