1,1,1,3,3,3-HEXAMETHYLDISILAZANE with cas 999-97-3

what is  of  1,1,1,3,3,3-HEXAMETHYLDISILAZANE with cas 999-97-3?

Hexamethyldisilazane is a bulk organo silicon compound, being a quite useful silanizing agent. It is a reagent for the preparation of trimethylsilyl derivatives. It can be used for silanizing the surface of silicon water, cellulose. It 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. It can also be used as a modifier to control the shape, formation of agglomerates surface area and pore size of silica particles. Moreover, it 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.
