Tetrabutylphosphonium cation is a pale orange solid with the formula [N(C4H9)4]Br3. It is a salt of the lipophilic tetrabutylammonium cation and the linear tribromide anion. The salt is sometimes used as a reagent used in organic synthesis as a conveniently weighable, solid source of bromine. References: Zhang T, Schwedtmann K, Weigand JJ, Doert T, Ruck M.
