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 N-(4-pentenyl) analog is a variant of XLR11 which replaces the N-(5-fluoropentyl) chain with N-(4-pentenyl). This analog is a commonly observed component of herbal mixtures (Spice/K2) containing synthetic CBs with the 5-fluoropentyl moiety, like XLR11, AM2201 , and MAM2201 . The biological and toxicological properties of this compound have not been evaluated. This product is intended for forensic and research applications.
