XLR11 is a synthetic cannabinoid (CB) featuring a tetramethylcyclopropyl group, which reportedly confers selectivity for the peripheral CB2 receptor over the central CB1 receptor. XLR11 also has an N-(5-fluoropentyl) chain, which increases binding to both CB receptors. XLR11 6-hydroxyindole metabolite is an expected minor monohydroxylated urinary metabolite of XLR11. The biological and toxicological properties of this compound have not been evaluated. This product is intended for forensic and research applications.
