Infobox references

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 DF(Methylphosphonyl difluoride), 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]
