'''''O''-Ethyl methylphosphonothioic acid''' (EMPTA) is an [[organophosphate compound]]. A dual-use chemical, it has constructive uses in the synthesis of pesticides and pharmaceuticals, and it is also a precursor in the synthesis of nerve agents such as [[VM (nerve agent)|Agent VM]] and [[VX (nerve agent)|Agent VX]]. The detection of EMPTA is cited as a major influence in the United States' 1998 decision to destroy the [[Al-Shifa pharmaceutical factory]] in Sudan.<ref>{{cite book | title = Weapons of mass destruction: an encyclopedia of worldwide policy, technology, and history | isbn = 1-85109-490-3
