Used as a specialized reagent in organometallic synthesis, particularly in the preparation of antimony-containing compounds for semiconductor and materials research. Its high reactivity with electrophiles and nucleophiles makes it valuable in the development of novel coordination complexes and catalysts. Also employed in vapor deposition processes for creating thin films with unique electronic properties. Due to its air and moisture sensitivity, it is handled under inert conditions, typically in glovebox or Schlenk-line setups.
