A certified solution standard suitable for use as starting material in calibrators and controls for GC/MS or LC/MS synthetic cannabinoid testing methods in forensic analysis, clinical toxicology, or urine drug testing. UR-144 5-Hydroxypentyl metabolite is a primary urinary metabolite of UR-144, a third generation synthetic cannabinoid that has seen wide popularity in illicit drug markets since late 2012. This biomarker is also referred to as the terminal omega hydroxyl metabolite of UR-144.

For those synthetic cannabinoids currently controlled at the federal level, our certified solution standards of these substances are DEA-exempt, allowing laboratories to place orders without additional regulatory paperwork. For US customers, state specific regulatory requirements may apply.
