 Amiton oxalate , its cas register number is 3734-97-2. It also can be called Amiton hydrogen oxalate ; Citram ; Hydrogen oxalate of amiton ; O,O-Diethyl S-(2-ethyl-N,N-diethylamino)phosphorothioate hydrogen oxalate ; O,O-Diethyl S-(beta-diethylamino)ethyl phosphorothiolate hydrogen oxalate ; O,O-Diethyl-S-(2-diethylamino)ethylphosphorothioate hydrogen oxalate ; S-(2-(Diethylamino)ethyl) O,O-diethyl phosphorothioate hydrogen oxalate ; Tetram ; Tetram monooxalate ; and Tetram, acid oxalate . It's Classification Code are Acaricide, Agricultural Chemical and Insecticide .The container of Amiton oxalate (CAS NO.3734-97-2) may explode in heat of fire.
 Organophosphates , such as [2-(diethylthiophosphor-S-yl)ethyl]diethylammonium hydrogen oxalate , are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
