UniqueCode:More infoUnique Lookup Code is an alphanumeric string created by the submitter and included with the sample so anonymously submitted samples can be positively identified as the submitter's sample. AC2021B1077
Marquis:More infoThe Marquis Test is a reagent field test conducted by placing a drop of reagent liquid onto a small sample of the material being tested. The chemicals in the reagent react differently with different chemicals, turning a variety of colors based on the what is in the material being tested. Unknown
Mecke:More infoAs with the Marquis Test, The Mecke Test is a reagent field test conducted by placing a drop of liquid reagent onto a sample of the material in question. Mecke reagent is primarily used for the identification of heroin and other opiates. Unknown
Mandelin:More infoThe Mandelin Test is a reagent field test conducted by placing a drop of liquid reagent onto a sample of the material in question. Mandelin is primarily used for the detection of ketamine and PMA. It is a mixture of ammonium metavanadate and concentrated sulfuric acid. Unknown

Lab comments:
The N-Phenethylpropanamide, 1-Phenethylpiperidin-4-ol, and 1-Phenethyl-4-propionyloxypiperidine were identified by library match.

Description
Off-white residue and cooker.
Note
August 9 2022: The unidentified substance is not fluoro-norfentanyl. It doesn't match the certified reference standard.

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.
Unidentifed Substances
This sample contains an unidentified chemical. We do not have a matching substance in our lab's internal database and have not yet been able to identify the chemical(s).

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.
