Mar 17 2022: A certified reference standard for Fluoro-norfentanyl is now available and has been ordered.
Oct 25 2021: Through DrugsData's expert network, we got a tentative identification of Fluoro-norfentanyl (CAS# 202859-51-6) for the unidentified substance with major ion 250.1 in this sample, presumably the para position since 4-fluoro fentanyl is also present. No reference standard is currently available for it in the U.S.
The unidentified substance with major ion 83 is likely N-(4-fluorophenyl)-N-(1-propionylpiperidin-4-yl)propionamide [the 'propionyl' fluoro-norfentanyl], which has no CAS#. There doesn't appear to be a certified reference standard for this, and this identification is unlikely to be confirmed until there is.
N-Phenethylpropanamide, 1-Phenethylpiperidin-4-ol, and 1-Phenethyl-4-propionyloxypiperidine also don't appear to be commercially available as certified reference standards at this time.
We need the help of outside expert analytical chemists and drug geeks to determine what substance matches the mass spectrum (MS) fingerprint. The lab's GC/MS graphs can be viewed by clicking on the thumbnails on this page.
