CS-27349, or L-2-α-tropinyl benzilate, is an experimental incapacitating agent. It acts as an antagonist to muscarinic acetylcholine receptors, causing delirium. It has 37% of the potency of the related compound 3-quinuclidinyl benzilate (BZ) in producing peripheral effects, but 85% of the potency in producing central effects. The mean dose required to incapacitate subjects was 1.2 times that of BZ.^[1] It has not been in use since the 1970s, and there have been no publications about its effects or long-term toxicology since then.^[2]
