| Technique | Typical performance | |-----------|---------------------| | | Detects parent compound after derivatization; LOD ≈ 0.1 ng μL⁻¹. | | LC‑MS/MS (ESI) | Preferred for biological matrices; MRM transitions: m/z 384 → 200 (base peak) and 384 → 166. LOD in urine ≈ 0.5 ng mL⁻¹. | | Immunoassay | Not widely available; cross‑reactivity with other indazole cannabinoids can cause false positives/negatives. | | NMR (¹H, ¹³C) | Useful for purity verification of synthetic batches (>95 % purity required for pharmacological work). |
