Isopropyl aminoethylmethyl phosphonite (NATO designation QL), also known as O-(2-diisopropylaminoethyl) O′-ethyl methylphosphonite, is a precursor chemical to the nerve agent VX and VR-56. It is a colorless liquid with a strong fishy odor, and is slightly soluble in water.[1]
Synthesis
QL is manufactured by reacting diethyl methylphosphonite with 2-(diisopropylamino)ethanol.[2]
Uses in chemical warfare
QL is a component in binary chemical weapons, mainly VX nerve agent.[3] It, along with methylphosphonyl difluoride (DF), was developed during the 1980s in order to replace an aging stockpile of unitary chemical weapons.[3] QL is listed as a Schedule 1 chemical by the Chemical Weapons Convention.[4]
Toxicity
QL itself is a relatively non-toxic chemical.[5] However, when reacting with sulfur, the corresponding sulfide of QL isomerizes into the highly toxic VX molecule.[3][5]
