1,3,5-Tribromobenzene(TBB) acts as internal standard during derivatization step in determination of cyanide in human plasma and urine by gas chromatography-mass spectrometry. TBB forms molecular complexes of 1:2 stoichiometry with [60]-and [70] fullerenes. TBB reacts with perfluoroalkenylzinc reagent in the presence of Pd(Ph3)4 catalyst to yield a novel trifunctional monomer 1,3,5-tris(α, β, β-trifluorovinyl)benzene.
