Reagents and standards of furanylFentanyl, 4-fluorobutyrFentanyl, acrylFentanyl, butyrylFentanyl, and 4-anilino-N-phenethyl-piperidine (4-ANPP) were produced by Chiron (Trondheim, Norway). AcetylFentanyl and carfentanil were obtained by Toronto Research Chemicals (North York, Canada) while ocfentanil and norFentanyl were purchased from Sigma-Aldrich (Milan, Italy). CyclopropylFentanyl, α-methylFentanyl, and β-hydroxyFentanyl were provided by National Institute of Health (ISS). Fentanyl and the deuterated internal standards (norFentanyl-d5, Fentanyl-d5) were produced by Cerilliant (Round Rock, Texas, USA). All other chemicals were purchased from Sigma-Aldrich (Milan, Italy). Ultra-pure water was obtained using a Milli-Q® UF-Plus apparatus (Millipore, Bedford, MA, USA). All stock standard solutions were prepared in methanol at 1 mg/mL and stored at − 20 °C until used. Working solutions were prepared at the final concentration of 1000 ng/mL by dilution with methanol.
Norfentanyl
Manufactured by Merck Group
Sourced in Canada
Norfentanyl is a chemical compound that is used as a laboratory standard and reference material. It is a metabolite of the opioid analgesic fentanyl. Norfentanyl is commonly used in analytical and forensic applications for the identification and quantification of fentanyl and related compounds.

(PBS) (1.8 mM KH2PO4, 10 mM Na2HPO4, 2.7 mM KCl, and 137 mM NaCl all from Fisher Scientific)
pH 7.4 were prepared with Millipore Milli-Q ultrapure water (18.2
MΩ cm). The GO suspension (Graphenea, particle size < 10
μm) was diluted from 4 mg/mL to a final concentration of 1 mg/mL
with PBS. Fentanyl, norFentanyl, alfentanil, carfentanil, lorazepam,
heroin, and cocaine were all sourced as analytical standards (1 or
0.1 mg/mL in methanol or acetonitrile) from Sigma-Aldrich (Cerilliant),
and caffeine and sucrose (from Sigma-Aldrich) were diluted to the
required final concentration with PBS (structures are shown inFigure 1 ).

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
