Used primarily in forensic and analytical research as a reference standard for identifying and quantifying synthetic cannabinoids in biological samples. Its labeled form (SP = stable isotope-labeled) makes it ideal for mass spectrometry applications, where accurate detection and differentiation from non-labeled analogs are critical. The trifluoroacetate (TFA) salt form enhances solubility and stability during sample preparation and instrument analysis. Commonly employed in toxicology labs and drug monitoring programs to improve the reliability of test results for emerging psychoactive substances.
