CAS 3279-26-3: Phosphorodichloridous acid, methyl ester

Description: Phosphorodichloridous acid, methyl ester, also known as methyl phosphorodichloridate, is an organophosphorus compound characterized by its phosphorus atom bonded to two chlorine atoms and a methyl ester group. This compound typically appears as a colorless to pale yellow liquid with a pungent odor. It is soluble in organic solvents but has limited solubility in water. The presence of the phosphorus atom imparts unique reactivity, making it a useful intermediate in the synthesis of various phosphorus-containing compounds, including pesticides and pharmaceuticals. Due to its chlorinated nature, it can be reactive, particularly with nucleophiles, and may pose health hazards, including toxicity if inhaled or ingested. Proper handling and storage are essential to mitigate risks associated with exposure. Additionally, it is important to note that this compound may be regulated under various chemical safety laws due to its potential environmental and health impacts. Always refer to safety data sheets and regulatory guidelines when working with such substances.
