Description

(+)-11-Nor-δ9-Tetrahydro Cannabinol-9-Carboxylic Acid CAS NO 114028-39-6 is a specific carboxylic acid metabolite of δ9-tetrahydrocannabinol (THC). This compound is of critical importance as a primary analytical reference standard for forensic and clinical toxicology testing. It is essential for laboratories and manufacturers requiring high-purity, well-characterized materials to ensure accurate quantification of THC exposure in biological matrices.

Application

• Primary Reference Standard for the calibration and validation of analytical methods (e.g., GC-MS, LC-MS/MS) in forensic toxicology.
• Quality Control Material for the production of immunoassay kits and point-of-care tests for drug screening.
• Research Chemical in pharmacokinetic and metabolic studies of cannabinoids within academic and pharmaceutical R&D.
• Manufacturing of Certified Reference Materials (CRMs) and proficiency testing samples for laboratory accreditation.
• Metabolite Standard for workplace drug testing programs and compliance monitoring.
• Method Development in clinical laboratories for monitoring patient compliance in medical cannabis programs.
