General description

An analytical reference standard suitable in cannabinoid testing, clinical toxicology, forensic analysis, or urine drug testing by LC-MS/MS or GC/MS. Also known as THC acid, 11-nor-9-Carboxy-Δ9-THC is the main secondary metabolite of THC found in urine or blood of cannabis users.

Application

  • Advanced analytical method development: A study by DeGregorio et al. introduces a Liquid Chromatography High-Resolution Mass Spectrometry (LC-HRMS) bioanalytical method for quantifying cannabinoids, including (−)-11-nor-9-Carboxy-Δ?-THC, in whole blood. This method is pivotal for determining recent cannabis use, offering significant advancements in forensic toxicology and drug testing (DeGregorio et al., 2020).
  • Cannabinoid serum analysis: Gottardo et al. present the first application of atmospheric-pressure chemical ionization gas chromatography tandem mass spectrometry for the determination of cannabinoids in serum. This groundbreaking technique enhances the detection and quantification of cannabinoids, including (−)-11-nor-9-Carboxy-Δ?-THC, facilitating deeper insights into cannabinoid pharmacokinetics and toxicology (Gottardo et al., 2019).

The guidelines for screening of urinary cannabinoids require that all specimens testing positive should be confirmed by gas chromatography-mass spectrometry at a confirmatory test cutoff value of 15 ng/mL of 11-nor-9-carboxy-Δ9-tetrahydrocannabinol (THCCOOH). To assess the impact of lowering the confirmatory

A new procedure is described for the derivatization by silylation of 11-nor-Δ(9)-tetrahydrocannabinol-9-carboxylic acid (THCCOOH) present in urine, followed by analysis using gas chromatography-tandem mass spectrometry. A conventional procedure for derivatization of the analyte was evaluated using two types of experimental
