General description

11-nor-9-Carboxy-Δ9-THC, also known as THC acid, is the main secondary metabolite of Δ9-THC found in urine or blood of cannabis users. This certified reference solution is suitable as starting materials in the preparation of calibrators and controls for THC testing by GC/MS or LC/MS in forensic analysis, urine drug testing, or clinical toxicology.

Application

  • Development and Validation of LC-HRMS for Cannabinoids in Whole Blood: This study introduces a liquid chromatography high-resolution mass spectrometry (LC-HRMS) method for quantifying cannabinoids, demonstrating its application in determining recent cannabis use, highlighting the relevance of THC metabolites like (±)-11-nor-9-Carboxy-Δ9-THC as analytical standards (DeGregorio et al., 2020).
  • Enhanced LC-MS-MS Technique for Distinguishing Tetrahydrocannabinol Isomers: Research focused on an improved LC-MS-MS method capable of distinguishing Δ8- and Δ9-tetrahydrocannabinol isomers in biological specimens, pertinent for forensic toxicology using standards such as (±)-11-nor-9-Carboxy-Δ9-THC (Reber et al., 2022).
  • Toxicogenetic Analysis of Δ9-THC-metabolizing Enzymes: This study explores the metabolism of THC, providing insights into the toxicogenetics of cannabinoid-metabolizing enzymes, relevant for drug metabolism studies using (±)-11-nor-9-Carboxy-Δ9-THC as a reference material (Gasse et al., 2020).
