2-FLUORODESCHLOROKETAMINE (2-FDCK) is a dissociative anesthetic.It is an analogue of ketamine where the chlorine group has been replaced by fluorine.
2-FLUORODESCHLOROKETAMINE (2-FDCK) 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.
There is very little information on the pharmacology, metabolism or toxicity of 2-FLUORODESCHLOROKETAMINE (2-FDCK). It has an extremely brief history of human use. It is strongly advised to use harm reduction practices if using this substance.
2-FLUORODESCHLOROKETAMINE (2-FDCK) is classed as anarylcyclohexylaminedrug. Arylcyclohexylamines drugs are named for their structures which include a cyclohexane ring bound to an aromatic ring along with an amine group. 2-FDCK contains a phenyl ring bonded to a cyclohexane ring substituted with a ketone group (cyclohexanone). An amino methyl chain (-N-CH3) is bound to the adjacent alpha carbon (R2) of the cyclohexanone ring. Additionally, the phenyl ring is substituted at R2with a fluorine group.
2-Fluorodescholoroketamine is a chiral molecule and is often produced as a racemate. Des- is a prefix used in chemistry to denote the absence of a functional group (in this case “chloro”) hence 2-FDCK is named for containing a fluorine substitution at its phenyl ring rather than the chlorine which is found inketamine.
Dangerous interactions
Although many psychoactive substances are reasonably safe to use on their own, they can quickly become dangerous or even life-threatening when taken with other substances. The following lists some known dangerous combinations, but cannot be guaranteed to include all of them. Independent research shouldalwaysbe conducted to ensure that a combination of two or more substances is safe to consume. Some interactions listed have been sourced from TripSit.
Stimulants– Both stimulants and dissociatives carry the risk of adverse psychological reactions like anxiety, mania, delusions and psychosis and these risks are exacerbated when the two substances are combined.
Depressants– Because both depress the respiratory system, this combination can result in an increased risk of suddenly falling unconscious, vomiting and choking to death from the resulting suffocation. If nausea or vomiting occurs, users should attempt to fall asleep in the recovery position or have a friend move them into it.
