 UR-144
100 µg/mL in Methanol | Certified Reference Material
UR-144 is a synthetic cannabinoid of the tetramethylcyclopropyl series. Along with XLR-11, cyclopropyl Spice analogs have seen wide popularity in the illicit markets since late 2012. UR-144 was originally developed as a pharmaceutical drug candidate due to its 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.
