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.]
