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.
