General description

Sodium tetraethylborate (NaBEt4) is an air and moisture-sensitive pyrophoric organoboron compound. It is very reactive in the presence of certain organometallic species and is used as an ethyl transfer reagent.

Application

Sodium tetraethylborate can be used as a derivatizing agent in the GC-MS analyses of fenbutatin oxide and alkyl tin compounds.

Monobutyltin (MBuT), dibutyltin (DBuT), and tributyltin (TBuT) mixtures have been separated and quantified by gas chromatography with pulsed flame-photometric detection (GC-PFPD). The compounds were first derivatized with NaBEt4, then extracted with hexane and injected into the GC in splitless mode.
