- TMSCl + NaN3 → TMSN3 + NaCl (TMS = (CH3)3Si)
It is considered a safer replacement for hydrazoic acid in many reactions. It will however over time hydrolyze to hydrazoic acid and therefore it must be stored free of moisture  It has been used in the Oseltamivir total synthesis.
Trimethylsilyl azide is incompatible with moisture, strong oxidizing agents, and strong acids.
