(-)-Δ9-THC-D3 (CAS 81586-39-2) is a high-purity analytical reference standard with the molecular formula C21H27D3O2 and a molecular weight of 317.48 g/mol.
Based on its molecular formula C21H27D3O2, (-)-Δ9-THC-D3 contains deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 317.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), (-)-Δ9-THC-D3 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
