CBNP.Cannabiphorol

CBNP (cannabiphorol) is the heptyl (C7) homologue of cannabinol: the same aromatic benzo[c]chromene nucleus, with a seven-carbon chain instead of five. The suffix « phorol » has denoted the heptyl series since the description of THCP and CBDP (Citti et al., 2019). In cannabis, only the corresponding acid, CBNPA, has been identified, and only putatively by high-resolution mass spectrometry, without isolation (Linciano et al., 2021). ChEMBL links 1983 rat data to this structure: by the oral route, a fall in systolic blood pressure and in spontaneous motor activity (Zaugg and Kyncl). No measurement of affinity for cannabinoid receptors, no pharmacokinetic data and no human study were found. No reliable source documents the origin of products sold under this name either. In France, it falls within the generic class of benzo[c]chromene derivatives in force since June 2024.

Origin not established: no reliable source documents its natural occurrence or where products sold under this name come from; only its acid (CBNPA) has been putatively identified in cannabis

No characterised biosynthesis. CBNP is the heptyl (C7) homologue of cannabinol. Only the corresponding acid, CBNPA, has been putatively identified by high-resolution mass spectrometry in cannabis samples, without isolation (Linciano et al., 2021).

European Union

Not listed in the UN conventions; no EU-specific control measure was found. Checked on 20/10/2026.

France

Narcotic through a generic class, without a named listing: it meets the definition of benzo[c]chromene derivatives (Annex IV, ANSM decisions of 22 May and 3 June 2024: hydroxyl at 1, alkyl chain at 3, two alkyls at 6, alkyl at 9), whose exclusion covers only CBN and CBNA, not their homologues. Checked on 20/10/2026.

Natural trace reported

Only the corresponding acid, cannabinophorolic acid (CBNPA), has been putatively identified by UHPLC-HRMS in Cannabis sativa samples, without isolation or a reference standard (Linciano 2021). No detection of neutral CBNP was found.
