RCS-4 N-(5-hydroxypentyl) metabolite-d5 contains five deuterium atoms at the 2, 4, 5, 6, and 7 positions. It is intended for use as an internal standard for the quantification of RCS-4 N-(5-hydroxypentyl) metabolite by GC- or LC-mass spectrometry. 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.1 RCS-4 N-(5-hydroxypentyl) metabolite is a potential metabolite of RCS-4. A similar JWH metabolite has been detected in human urine following JWH smoking.2 This metabolite is almost completely glucuroconjugated in urine samples, requiring enzymolysis of the sample before analysis.2
