Dimethylamidophosphoric dichloride is a chemical used in industrial applications. It is used for synthesizingphosphoramidates as well astabun, which is used as achemical weapon.[2]
Due to its nature, this chemical iscorrosive,flammable, andneurotoxic if ingested or absorbed through the skin.[3] In contact with water, it is expected to give offhydrogen chloride anddimethylamidophosphoric acid vapors.[4]
First synthesis of the substance dates back to turn of the 19th century, when a student of German chemistry professorAugust Michaelis Ernst Ratzlaff made dimethylamidophosphoric dichloride as well as its diethyl analog for experiments of another PhD student of Michaelis Adolph Schall.[5] He obtained a PhD atUniversity of Rostock with a thesis titledÜber die Einwirkung primärer und sekundärer Amine auf Phosphoroxychlorid und Äthoxylphosphoroxychlorid later in 1901. The high toxicity of the substance (as well as the high toxicity of ethyl diethylaminocyanophosphonate, an analog oftabun synthesised by Schall) wasn't noticed at the time, most likely due to the low yield of synthetic reactions used.
