2FDCK, or 2-Fluorodeschloroketamine, is a chemical analog of ketamine with a modification that replaces a chlorine atom with a fluorine atom on the phenyl ring.

This compound is known for its dissociative properties and is used primarily in scientific research to study its effects on the brain and potential applications in medicine.

More information about 2fdck:

2-Fluorodeschloroketamine(2-fdck), or 2-(2-Fluorophenyl)-2-methylamino-cyclohexanone, is classed as an arylcyclohexylamine research chemical. Arylcyclohexylamines research chemicals 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 R₂ with 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 in other substances.
