Documented Uses

• A byproduct from the manufacture of the nerve-agent Sarin (constitutes up to 20% of Sarin); [HSDB]
• May be used to simulate G-type chemical agents
• Phosphonic acid, P-methyl-, bis(1-methylethyl) ester: ACTIVE
• Diisopropyl methylphosphonate is a byproduct from the manufacture of the nerve-agent Sarin
• ... Three dose levels of diisopropyl methylphosphonate were applied to a shaved area on the backs of Yorkshire-Cross pigs: 400, 40, and 4 ug/sq cm. Additional animals were given 40 mg of diisopropyl methylphosphonate by sc injection, which was equivalent to the high dose applied dermally. Within 24 hr of injection, 91% of the sc administered dose was eliminated in the urine. After 5 days, no further amt was detected in the urine. All tissue specimens collected revealed less than 0.04 ug/g of tissue. For those pigs
• Single doses (225 mg/kg) of [14C]-radiolabeled diisopropyl methylphosphonate dissolved in polyethylene glycol were admin by gavage to fasted male mice, rats, and dogs ... In mice, the highest level of radioactivity (172 ug/ml) was noted in the blood at 15 min. In rats, plasma concn peaked at 151 ug/ml about 2 hr after cmpd admin ... In dogs, peak plasma concn also occurred at 2 hr post-admin at a concn of 276 ug/ml ... Approx 90% of the diisopropyl methylphosphonate was absorbed from the GI tract. This estimate is
