Extracted Ion Chromatogram (XIC) obtained from an authentic rat plasma specimen. Blood was collected 8 h after 0.3 mg/kg AM-2201 subcutaneous injection. AM-2201 (quantification transition A1 and qualification transition A2), JWH-018 N-(5-hydroxypentyl) (B1 and B2), and JWH-018 N-pentanoic acid (C1 and C2) concentrations were 6.5, 0.2, and 0.4 μg/L, respectively. Plain black line indicates raw data signal; dashed horizontal line indicates signal baseline; blue area indicates the actual peak integration; CPS, count per second.
