Industrial Applications
Diethyl Chlorophosphate serves primarily as a building block in the production of organophosphate pesticides. It is a documented intermediate in the synthesis of Phosfolan (CAS 947-02-4) and Mephosfalan (CAS 950-10-7)—compounds historically used in agricultural pest control formulations. Its role involves phosphorylation and chlorination steps that enable the introduction of ethoxyphosphoryl moieties into complex organic frameworks.
Key advantages of this intermediate include:
- High functional group compatibility in multi-step syntheses
- Controlled reactivity under anhydrous conditions
- Scalable handling in standard chemical manufacturing infrastructure
For safe handling, store in a cool, well-ventilated area away from moisture, heat sources, and incompatible materials such as strong bases or nucleophiles. Standard packaging is 25 kg drums, with custom configurations available upon request.
