Hexamethyldisilazane

Hexamethyldisilazane is an organosilicon compound. The molecule is a derivative of ammonia with trimethylsilyl groups in place of two hydrogen atoms. This colorless liquid is a reagent and a precursor to bases that are popular in organic synthesis and organometallic chemistry. In photolithography, hexamethyldisilazane is often used in as an adhesion promoter for photoresist. In electron microscopy, it can be used as an alternative to critical point drying during sample preparation. In pyrolysis-gas chromatography-mass spectrometry, hexamethyldisilazane is added to the analyte to create sylilated diagnostic products during pyrolysis, in order to enhance detectability of compounds with polar functional groups.

Hexamethyldisiloxane

Hexamethyldisiloxane is a chemical compound with the formula O[Si(CH3)3]2. This volatile liquid is used as a solvent and as a reagent. HMDS is used as an internal standard for calibrating chemical shift in1H NMR spectroscopy. It is more easily handled since it is less volatile than the usual standard tetramethylsilane but still displays only a singlet near 0 ppm.
