Latest Patents

John P Testa, Jr. holds a patent for a compound titled "Sn-labelled tetra-n-butyltin and tri-n-butyltin bromide." This invention involves the synthesis of stable isotope-labelled tetra-n-butyl(124)tin through the reaction of n-butylmagnesium bromide with SnCl4. Additionally, tri-n-butyltin bromide is synthesized via bromine cleavage of the tetraalkyltin. The tri-n-butyl(124)tin compound, labelled with the stable isotope Sn, is utilized to trace the fate, uptake, and metabolism of tributyltin compounds. This determination is achieved through gas chromatography (GC) and electron impact low-resolution mass spectrometry (MS). The isotopically enriched compounds provide a twofold increase in detection sensitivity using these techniques.
