Study on the mass fragmentation pathway of the synthetic cannabinoids JWH-018 and JWH-073

- Certain characteristic fragmentation pathways were proposed for the first time.
- The MS/MS data and accurate mass measurements were combined to create the fragmentation pathways of JWH-018 and JWH-073.
- The fragmentation pathways were proposed based on the high-resolution gas chromatography-mass spectrometry studies and elemental composition analyses.
- Explain the mass fragmentation pathway of m/z 167 by synthesis Compound A.
- Explain the mass fragmentation pathway of dehydroxylation.
