General description

It is an internal standard of Δ9-THC, the main active constituent and the primary psychoactive cannabinoid of cannabis.


This Certified Spiking Solution® is suitable as an internal standard for quantitation of Δ9-THC levels in urine or other matrices by LC/MS or GC/MS for pharmaceutical research, clinical toxicology, or forensic testing applications.

The Certified Reference Material (CRM) in solution can also be used as follows:

  • Development of an automated sample preparation method based on solid phase extraction (SPE) to determine ∆9-tetrahydrocannabinol (THC) and its three primary metabolites in a variety of matrices, such as serum, saliva, and urine using liquid chromatography-mass spectrometry (LC-MS)
  • Comparative analysis of two methods based on ultra high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method and solid phase microextraction-gas chromatography-mass spectrometry (SPME-GC/MS) to measure cannabinoids in oral fluid samples of small volumes
  • As an internal standard in high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) based quantitative assay of 11 cannabinoids and their metabolites in human urine and plasma samples

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
