Described is a procedure for synthesis of 117Sn tributil butyltin. Synthesis starts with bromination of metallic Sn, followed by butylation with butyl lithium. The formed tetrabutyltin (SnBu4) was transformed to tributyltin chloride (TBTCl) using concentrated hydrochloric acid (HCl). The purity of synthesized TBT was verified by the speciation analysis using gas chromatography coupled to inductively coupled plasma mass spectrometry (GC-ICP-MS) and nuclear magnetic resonance (NMR) techniques. Data revealed that TBT has a purity of more than 93 %. The remaining 7 % corresponded to DBT. TBT was quantified by reverse isotope dilution GC-ICP-MS. The synthesis yield was better than 60 % and the stability of product more than 6 months.
