2-Fluorodeschloroketamine is a dissociative substance of the arylcyclohexylamine class, structurally related to ketamine with the chlorine group replaced by fluorine. It first appeared on the research chemical market around 2017, marketed as a legal replacement for ketamine. Its effects are reported to be similar to ketamine and highly dose-dependent, ranging from alcohol-like intoxication at lower doses to hallucinogenic out-of-body dissociative states at higher doses. Research on its pharmacology remains limited.
Also known as: 2-Fluorodeschloroketamine, 2f-ket, 2f-ketamin, 2-fl-2'-oxo-pcm, 2-fluoro-2-oxo-pcm, 2-(2-fluorophenyl)-2-methylamino-cyclohexanone, 2-Fluoroketamine, 2-FK
