RCS-4 (Item No. 10645) is a synthetic cannabinoid (CB) that has been detected as an adulterant of herbal mixtures.¹ RCS-4 2-methoxy isomer is an analog of RCS-4 that differs only in the location of the methoxy group on the phenyl ring. The affinity of RCS-4 2-methoxy isomer for CB receptors, or its physiological effects, have not been documented. However, RCS-4 2-methoxy isomer structurally resembles JWH 250 (Item No. 13634), a cannabimimetic indole that shows a high-affinity for both CB₁ and CB₂ (K_i = 11 and 33 nM, respectively).²
