Isopropyl aminoethylmethyl phosphonite (NATO designation QL), also known as O-(2-diisopropylaminoethyl) O'-ethyl methylphosphonite, is a precursor chemical to the nerve agent VX.
Uses in chemical warfare
QL is a component in binary chemical weapons, mainly VX nerve agent.[1] It, along with Methylphosphonyl difluoride (DF), was developed during the 1980s in order to replace an aging stockpile of unitary chemical weapons.[1] QL is listed as a "Schedule One" chemical by the Chemical Weapons Convention.[2]
Toxicity
QL itself is relatively non-toxic chemical.[3] However, when reacted with sulfur, the corresponding sulphide of QL isomerizes into the highly toxic VX molecule.[1][3]
