(-)-11-nor-9-carboxy-δ9-THC-d3 (exempt preparation)

(−)-11-nor-9-carboxy-Δ⁹-THC-d₃ (exempt preparation) contains three deuterium atoms at the 5 position. It is intended for use as an internal standard for the quantification of (−)-11-nor-9-carboxy-Δ⁹-THC (exempt preparation) by GC- or LC-mass spectrometry. Δ⁹-Tetrahydrocannabinol (Δ⁹-THC), the active constituent of marijuana, is metabolized primarily by hydroxylation at the allylic C-11 position followed by oxidation to (−)-11-nor-9-carboxy-Δ⁹-THC. (−)-11-nor-9-carboxy-Δ⁹-THC is the major metabolite of Δ⁹-THC and is used as an internal standard in various analytical procedures to unequivocally confirm its presence in biological fluids.¹
