Notes: RCS-4 is structurally similar to certain JWH compounds, synthetic cannabinoids used in herbal mixtures meant to mimic cannabis. RCS-4 itself has been identified in herbal mixtures.{19508} RCS-4 N-(5-hydroxypentyl) metabolite (Item No. 10935) is a potential metabolite of RCS-4. A similar JWH metabolite has been detected in human urine following JWH smoking.{18291} This metabolite is almost completely glucuroconjugated in urine samples, requiring enzymolysis of the sample before analysis.{18291} This product is intended for research and forensic applications.
