CAS 2283-11-6: Hexaethylphosphorous triamide

Hexaethyl phosphorous triamide is used in the Barton syntheses of hindered alkenes, involving desulfurization of small-ring heterocycles with elimination of nitrogen or carbon dioxide. It is also used as a reagent for selective vicinal dehalogenation of halogenated alkanes to give perhalogenated alkenes. The method has potential for the synthesis of highly fluorinated and mixed fluoro-halo alkenes. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio.

Hexaethylphosphorous triamide (HEPTA) is a compound that contains a carbonyl group, carboxylic acid, and an activated hydrogen. It is used in chemical synthesis as an activating reagent for hydrogen fluoride to form chloroform. HEPTA is also used as a high-temperature solvent for reactions involving alkanoic acids and cyclohexane rings. It has shown to have good chemical stability and reaction mechanism. In addition, HEPTA has been shown to be carcinogenic in animal studies and may be related to bladder cancer or other cancers with fatty acid metabolites. HEPTA can cause DNA damage by reacting with chlorine atoms from the environment or fatty acid in the bladder. This can lead to mutations in the genome of cells which can lead to cancer development.
