Description

(-)-11-Nor-δ9-Tetrahydro Cannabinol-9-Carboxylic Acid CAS NO 1262438-64-1 is a major carboxylic acid metabolite of δ9-Tetrahydrocannabinol (THC). This compound is of critical importance as a reference standard and analytical marker for forensic, clinical, and workplace drug testing. It is primarily required by toxicology laboratories, diagnostic kit manufacturers, and pharmaceutical research organizations for the accurate quantification of THC exposure.

Application

• Forensic Toxicology Reference Standard: Primary metabolite used for calibrating equipment and validating methods in urine drug tests for cannabis use.
• Clinical Diagnostic Reagent: Critical component in the development and quality control of immunoassay kits and LC-MS/MS panels.
• Workplace Drug Testing: Essential for establishing cutoff levels and ensuring compliance with regulatory standards for employee screening programs.
• Pharmacokinetic and Metabolism Studies: Used in pharmaceutical R&D to study the metabolic pathways and clearance of cannabinoids.
• Method Development and Validation: Serves as a certified reference material (CRM) for laboratories establishing new analytical protocols.
• Quality Control and Proficiency Testing: Employed in inter-laboratory comparison programs to ensure accuracy and reliability of test results across facilities.
