Trimethylsilyl azide

Trimethylsilyl azide ((CH3)3SiN3) is a chemical compound used as a reagent in organic chemistry. It can be produced from trimethylsilyl chloride and sodium azide It is considered a safer replacement for hydrazoic acid in many reactions. It will however over time hydrolyze to hydrogen azide and therefore it must be stored free of moisture. For an example of its use: see Oseltamivir total synthesis.
