An internal standard suitable for quantitation of UR-144 5-pentanoic acid metabolite levels using LC-MS/MS or GC/MS for synthetic cannabinoid testing methods in forensic analysis, clinical toxicology, or urine drug testing. UR-144 5-pentanoic acid 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.

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.
