General description

exo-THC, also known as ∆9-11-THC, occurs as an impurity of ∆9-THC formed during its synthesis.


The Certified Spiking Solution® is suitable for exo-THC testing by HPLC, GC/MS, or LC-MS/MS methods in forensic analysis, clinical toxicology, urine drug testing, and cannabis potency or impurity profiling testing applications. The Certified Reference Material (CRM) in solution can also be used as follows:
  • Analysis of 29 hemp-based veterinary products to measure the amount of cannabinoids, terpenes, and heavy metals by liquid chromatography-diode array detection/mass spectroscopy (LC-DAD/MS), headspace gas chromatography-flame ionization detection (HS-GC-FID), and inductive coupled plasma-mass spectroscopy (ICP-MS)
  • Identification of 24 non-psychoactive cannabinoids in Cannabis Sativa extracts by liquid chromatography-UV detector and using linear retention index (LRI) approach

Features and Benefits

  • Fully characterized under ISO/IEC 17025 and ISO 17034 accreditation
  • Accompanied with a comprehensive Certificate of Analysis (CoA) with data on stability, homogeneity, accuracy of concentration, uncertainty, and traceability
  • Rigorously tested through real-time stability studies to ensure accuracy and shelf life
  • Gravimetrically prepared using qualified precision balances to ensure minimal uncertainty
  • Flame sealed under argon into ampoules for long-term shelf life
  • Offered in a convenient, DEA-exempt format to improve laboratory efficiency

The present studies examine some of the pharmacological effects of delta-9 (11)-tetrahydrocannabinol (delta 9-11-THC), an analog of delta-9-tetrahydrocannabinol (delta 9-THC). In tests with mice, delta 9-11-THC was similar to but less potent than delta 9-THC in producing hypothermia, analgesia, lethality
