Close
Naled is stable in anhydrous condition and must be stored away from light. It must also be stored under normal pressure and temperatures. It degrades in the presence of water and alkali, and produces toxic chloride fumes if exposed to acids or acidic fumes. Contact with metals, reducing agents, or sulfhydryls cause naled to release bromide and revert to dichlorvos.[4]
