Ammonium O,O-diethyl dithiophosphate , its cas register number is 1068-22-0. It also can be called Phosphorodithioic acid, O,O-diethyl ester, ammonium salt ; S-Ammonium O,O'-diethyl phosphorodithioate ; and Ammonium ethyl phosphorodithioate (6CI,7CI) . It is hazardous, so the first aid measures and others should be known. Such as: When on the skin: first, should flush skin with plenty of water immediately for at least 15 minutes while removing contaminated clothing. Secondly, get medical aid. Or in the eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Then get medical aid soon. While, it's inhaled: Remove from exposure and move to fresh air immediately. Then you have the ingesting of the product: Wash mouth out with water, and get medical aid immediately.
In addition, Ammonium O,O-diethyl dithiophosphate (CAS NO.1068-22-0) could be stable under normal temperatures and pressures. It is not compatible with strong oxidants. And also prevent it to broken down into hazardous decomposition products: irritating and toxic fumes and gases.
