Hexamethylphosphorous triamide Chemical Properties,Uses,Production

Chemical Properties

colourless liquid


A compound widely used in industry, with applications such as being a flame retardant for building materials to a phosphorylating agent in synthetic chemistry. It is a classified carcinogen.


suzuki reaction


Reagent combination with CCl4 for the conversion of hydroxyl groups to the corresponding chlorides; hydroxyl group activation; dehydrations.

Purification Methods

It may contain more than 1% of phosphoric triamide. The yellow oil is first distilled at atmospheric pressure, then under reduced pressure and stored under N2. It is air sensitive, TOXIC, and should not be inhaled. It is absorbed through the skin. [Mark Org Synth Coll Vol V 602 1973, Beilstein 4 IV 274.]
