Description

(+/-)-11-Nor-9-Carboxy-Delta9-Thc CAS NO 104874-50-2 is a primary carboxylic acid metabolite of δ-9-tetrahydrocannabinol (THC). This compound is of critical importance as a reference standard and analytical marker in forensic and clinical toxicology. It is essential for laboratories and manufacturers requiring precise calibration for the detection and quantification of THC exposure in biological matrices.

Application

• Forensic Toxicology Reference Standard: Primary calibrant for the confirmation of cannabis use in urine, blood, and hair analysis.
• Clinical Research & Diagnostics: Used in the development and validation of immunoassays and chromatographic methods (LC-MS/MS, GC-MS) for drug testing.
• Pharmaceutical Impurity Profiling: Serves as a known impurity or degradation product in the quality control of cannabinoid-based APIs and finished drug products.
• Workplace & Sports Drug Testing: Critical component in kits and systems designed for compliance and anti-doping programs.
• Metabolite Studies: Used in pharmacokinetic and metabolic pathway research for cannabinoids.
• Calibration & Proficiency Testing: Provides traceable accuracy for laboratory accreditation (ISO/IEC 17025) and quality assurance schemes.
