JWH 203 N-pentanoic acid metabolite-d5

JWH 203 N-pentanoic acid metabolite-d5 (Item No. 14369) is intended for use as an internal standard for the quantification of JWH 203 N-pentanoic acid metabolite (Item No. 14229) by GC- or LC-MS. JWH 203 is an analgesic chemical from the phenylacetylindole family that acts as a cannabinoid (CB) agonist with Ki values of 8.0 and 7.0 nM at the central (CB1) and peripheral (CB2) receptors, respectively.1 Similar to the related 2'-methoxy compound JWH 250 (Item No. 13634), JWH 203 has a phenylacetyl group in place of the naphthoyl ring used in most aminoalkylindole CB compounds. Compared to JWH 250, JWH 203 displays slightly more potent binding affinities for the CB1 and CB2 CB receptors (JWH 250 Kis = 11 and 33 nM, respectively).1 JWH 203 N-(5-hydroxypentyl) metabolite is expected to be a metabolite of JWH 203 that would be detectable both in serum and in urine. JWH 203 (Item No. 9000736) is a synthetic cannabinoid (CB) that displays high affinities for both the central CB1 receptor (Ki = 8.0 nM) and the peripheral CB2 receptor (Ki = 7.0 nM).1 JWH 203 N-pentanoic acid metabolite is an expected metabolite of JWH 203, based on the metabolism of similar compounds.2 The physiological and toxicological properties of this compound have not been characterized. This product is intended for forensic and research purposes.WARNING This product is not for human or veterinary use.
