Hexamethyldisilazane is a colorless liquid with a strong ammonia odor. It is basic and can react with acids to form salts. It can also undergo nucleophilic substitution reactions and can participate in electrophilic substitution reactions. It is a relatively stable compound and can be stored at room temperature. It is sensitive to oxygen and water and is susceptible to oxidation and hydrolysis.
Hexamethyldisilazane is most commonly used as a primer layer to increase the adhesion of photoresist on pinwheel surfaces.
It is also widely used in the field of organic synthesis, and can be used as an alkali catalyst, an intermediate in organic synthesis and a reaction aid.
Hexamethyldisilazane can also be used as a protective group for organosilicon compounds, playing the role of protecting load and protecting functional groups in the synthesis.
