Perfluorotributylamine

Perfluorotributylamine (PFTBA), also referred to as FC43, is an organic compound with the chemical formula N(CF2CF2CF2CF3)3. It is a colorless liquid. A molecule of this chemical compound consists of three butyl groups connected to one nitrogen atom, in which all of the hydrogen atoms are replaced with fluorine atoms. The compound is produced for the electronics industry, along with other perfluoroalkylamines. The high degree of fluorination significantly reduces the basicity of the central amine due to electron-withdrawing effects.
