General description

Tributylamine is a tertiary amine. It has been reported to prevent the corrosion of mild steel in HCl solution.[1]

Application

Tributylamine (n-Bu3N) has been used to compose the mobile phase for the liquid chromatography tandem mass spectrometry (LC-MS/MS) analysis.[2]
It may be used in the preparation of PdCl,N and PdOAc,N (palladium nanoparticles).[3] It may be used as an additive during the synthesis of 3-bromothieno[3,2-c]pyridine-4-(5H)-one.[4]

Amphetamine-like psychostimulants are thought to produce rewarding effects by increasing dopamine levels at mesolimbic synapses. Paradoxically, dopamine uptake blockers, which generally increase extracellular dopamine, inhibit amphetamine-induced dopamine overflow. This effect could be due to either inhibition of amphetamine uptake or
