A method of synthesis of tributyl[113Sn]tin,(n/C4H9)3113Sn(IV), from commercially avail-able inorganic 113Sn(IV) is presented. Inorganic tin is first extracted in diethyl ether and reacted with C4H9MgCl to produce tetrabutyltin, (C4H9)4113Sn, which is then debutylated with HgCl2. The resulting tributyl[113Sn]tin chloride is isolated from the reaction mixture by successive extractions with hexane and aqueous Na2S2O3. The yield is 40-60% and the product obtained is 〉98% pure. It has the same specific activity as the starting 113Sn(IV), i.e. up to 550 MBq mg-1 Sn, making it suitable for use in environmental fate and toxicology studies at concentrations relevant of those found in the aquatic environment. © 1998 John Wiley & Sons, Ltd.
