2-Fl-2′-Oxo-PCM  (also known as 2-Fluorodeschloroketamine,  2-FDCK,  and inaccurately as 2-Fluroketamine,  Fluoroketamine,  and 2-FK)  is a lesser-known novel dissociative substance of the arylcyclohexylamine class that produces dissociative,  anesthetic,  and hallucinogenic effects when administered.  It is structurally related to arylcyclohexylamines like ketamine and deschloroketamine and is reported to produce similar effects.

Like other dissociative substances,  it is primarily sought by recreational users for its ability to induce a hallucinogenic  “out of body”  state referred to as  “dissociative anesthesia”  (although the extent to which this occurs is highly dose-dependent).  It has recently become available through online research chemical vendors where it is being sold as a designer drug replacement for ketamine.
