JWH 073 7-hydroxyindole metabolite-d7

JWH 073 7-hydroxyindole metabolite-d₇ contains seven deuterium atoms at the 2, 2', 3, 3', 4, 4, and 4 positions. It is intended for use as an internal standard for the quantification of JWH 073 7-hydroxyindole metabolite by GC- or LC-mass spectrometry (MS). JWH 073 is a mildly selective agonist of the central cannabinoid (CB₁) receptor derived from the aminoalkylindole WIN 55,212-2. The K_i values for binding CB₁ and the peripheral cannabinoid (CB₂) receptor are 8.9 and 38 nM, respectively for a CB₁:CB₂ ratio of 0.23.¹ JWH 073 is one of several synthetic CBs which have been included in smoking mixtures. JWH 073 7-hydroxyindole metabolite is expected to be a urinary metabolite of JWH 073 based on the metabolism of the closely-related JWH 015 and JWH 018.^2,3
