Application

Tetrabutylammonium cyanide (TBACN) can be used as a source of cyanide ion for colorimetric studies.
It can be employed as a reactant in the preparation of:
  • Tetrabutylammonium fluoride (TBAF), which can be used to remove silyl ether protecting groups.
  • Rhenium-based single-chain magnets, (DMF)4MReCl4(CN)2 (M = Mn, Fe, Co, Ni).
  • Phosphorescent blue light-emitting anionic iridium complexes.
