  • XLR11 N-pentanoic acid metabolite

UR-144 (Item No. 11502) is a potent synthetic cannabinoid (CB) which preferentially binds the peripheral CB2 receptor (Ki = 1.8 nM) over the central CB1 receptor (Ki = 150 nM).1 UR-144 N-pentanoic acid metabolite is an expected phase I metabolite of UR-144, based on the metabolism of similar cannabimimetics.2,3 This metabolite should be detectable in either serum or urine.2,3 The physiological and toxicological properties of this compound have not been tested. This product is intended for forensic and research applications.
