WebFentanyl, norfentanyl, acetyl fentanyl and acetyl norfentanyl spiked into whole blood were stable after three freeze-thaw cycles and at room temperature for 72 h (Poklis et al., 2015). No loss of fentanyl concentration could be observed after 3 months of storage at 4–8°C and −20°C in blood samples at 5 and 10 ng/mL (Andresen et al., 2012). Norfentanyl is an inactive synthetic opioid analgesic drug precursor. It is an analog and metabolite of fentanyl with the removal of the phenethyl moiety (or functional group) from fentanyl chemical structure.
WebUpon N-dealkylation, norfentanyl is formed, which is hypothesized to undergo a follow-up reversible redox reaction at the unsubstituted secondary amine with an E 1/2 of ca. 0.05 V vs. Ag/AgCl [44]. The voltammetry of fentanyl and its electroactive oxidation product, norfentanyl, thereby generates a specific “fingerprint” permitting differentiation from … WebFentanyl is also metabolized to norfentanyl in human duodenal microsomes; the mean rate is approximately half of the hepatic …
