O-2545 is an analgesic cannabinoid derivative created by Organix Inc. for use in scientific research. Unlike most cannabinoids discovered to date, it is water soluble, which gives it considerable advantages over many related cannabinoids. It has high affinity for both CB1 and CB2 receptors, with Ki values of 1.5nM at CB1 and 0.32nM at CB2.[1]
