Other Names: G3722
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. GKGBG
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. No Reaction
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. No Reaction
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. No Reaction

Lab comments:
Nov 7 2023: This sample is the subject of a case report published in Journal of Forensic Sciences in Aug 2023, which identifies the previously unidentified substances. Summary below in Note.

Unidentified Substance #1: 3 parts
Unidentified Substance #2: 2 parts
Unidentified Substance #3: 15 parts
Unidentified Substance #4: 1 parts
Unidentified Substance #5: 2 parts
Unidentified Substance #6: 7 parts
Description
Bar-style white tablet with G3722 on one side, break lines on both sides.
Note
Nov 2023 Summary: a failed synthesis of alprazolam, based on a questionable published procedure

Details:

unid 1: 2-amino-5-chlorobenzophenone

unid 2: N-(2-benzoyl-4-chlorophenyl)acetamide

unid 3 (major constituent): N-(2-benzoyl-4-chlorophenyl)-2-chloroacetamide

unid 4: Unconfirmed (Lowest intensity peak), tentatively identified as being from a dichloroacetylchloride impurity in the chloroacetylchloride that produced N-(2-benzoyl-4-chlorophenyl)-2,2-dichloroacetamide (unid 3).

unid 5: 2-(2-benzoyl-4-chloroanilino)-2-oxoethyl acetate

unid 6: sucrose octaacetate (a safe bittering agent)
Note
Sep 9 2022: According to one chemist, unidentified substance #1 is similar to 2-Amino-5-Chlorbenzophenone [CAS #719-59-5)], and #2 is similar to N-(2-benzoyl-4-chlorophenyl)acetamide [CAS# 13788-59-5] (thank you, Y.).

Jun 17 2022: Sucrose octaacetate matched for Unidentified #6. The DrugsData lab does not normally identify and report sugars. This version of sucrose is a bittering agent used in commercial products to reduce accidental ingestion. This is a special case, please do not ask us to identify simple sugars and salts. Update Jan 29, 2021: We have re-attempted to identify these and found no matches with updated libraries and hundreds of new reference standards added to our library since the first analysis. We will attempt again in the future.
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.
