EA-3167
EA-3167 is a potent and long-lasting anticholinergic deliriant drug, related to the chemical warfare agent 3-quinuclidinyl benzilate. It was developed under contract to Edgewood Arsenal during the 1960s as part of the US military chemical weapons program, in an attempt to develop non-lethal incapacitating agents. EA-3167 has identical effects to QNB, but is even more potent and longer-lasting, with an effective dose when administered by injection of as little as 2.5 μg/kg, and a duration of 120-240 hours. However unlike QNB, EA-3167 was never weaponized or manufactured in bulk.
Stereoisomers of EA-3167 have also been synthesized under the codename HL-031120.
