CF3CF2CF3

CF3CF2CF3, also known as perfluorotributylamine or FC-43, is a synthetic perfluorocarbon compound. It is a clear, colorless, and odorless liquid with a high density and low surface tension. Its chemical structure consists of a nitrogen atom bonded to three trifluoromethyl groups (CF3) and one perfluoroethyl group (CF2CF3). However, the common nomenclature often refers to the molecule as if it were derived from tributylamine, which is misleading given its perfluorinated nature.

Perfluorotributylamine is characterized by its exceptional chemical and thermal stability. It is inert to most acids, bases, and oxidizing agents. Its high boiling point and low vapor pressure make it suitable for applications requiring stability at elevated temperatures. Due to its non-flammable nature and excellent dielectric properties, it has found use as a heat transfer fluid and as an insulating medium in various electronic and electrical applications. Its biocompatibility has also led to investigations for use in medical applications, such as artificial blood substitutes, though its high cost and specific properties limit widespread adoption. The compound is typically synthesized through electrochemical fluorination processes.
