Description

11-Nor-δ9-Tetrahydro Cannabinol-9-Carboxylic Acid is a primary carboxylic acid metabolite of δ9-tetrahydrocannabinol (THC). This compound is of critical importance as a reference standard and analytical marker in forensic, clinical, and workplace drug testing programs. It is essential for laboratories and manufacturers requiring high-purity, well-characterized materials for method development, calibration, and quality control of immunoassays and chromatographic analyses.

Application

• Forensic Toxicology Reference Standard: Primary application for the quantification of THC metabolites in biological samples (urine, blood, hair) to confirm cannabis use.
• Clinical Research & Diagnostics: Used as a calibrator and control in developing and validating diagnostic assays for cannabinoid detection.
• Workplace & Sports Drug Testing: Critical component in the manufacture of test kits and the operation of certified testing laboratories.
• Pharmaceutical Impurity Profiling: Serves as a known impurity or degradation product in the analysis of synthetic cannabinoid pharmaceuticals.
• Metabolite Studies & Pharmacokinetics: Utilized in research to study the metabolism, distribution, and excretion of cannabinoids.
• Calibration of Analytical Instrumentation: Essential for ensuring the accuracy and reliability of HPLC, GC-MS, and LC-MS/MS systems in analytical laboratories.
