| Abstract | THCA-1 is a calibration solution certified reference material (CRM) for the cannabinoid delta-9-tetrahydrocannabinolic acid (Δ9-THCA), in acetonitrile. This material, distributed in 1 mL units, is intended for instrument calibration, method development, validation, and quantitation of Δ9-THCA in cannabis, hemp, and other cannabis-derived products. Certified values for the mass fraction and mass concentration of delta-9-tetrahydrocannabinolic acid in THCA-1 have been established. The information values for the mass fraction and mass concentration of minor impurities in THCA-1 are provided. |
