XLR-11 is a synthetic cannabinoid of the tetramethylcyclopropyl series found in newer Spice blends. Along with UR-144, cyclopropyl Spice analogs have seen wide popularity in the illicit markets since late 2012. XLR-11 is similar in structure to UR-144 and A-796,260, two compounds originally developed as pharmaceutical drug candidates due to their high affinity for the cannabinoid receptor CB2.
For those synthetic cannabinoids currently controlled at the federal level, our certified solution standards of these substances are DEA-exempt, allowing laboratories to place orders without additional regulatory paperwork. For US customers, state specific regulatory requirements may apply.
