Ehrlich's turns purple in the presence of LSD, helping rule out 25i-NBOMe, a highly toxic and extremely dangerous drug often misrepresented as LSD. INCLUDES A FREE FENTANYL TESTING STRIP! Contains enough reagent for approximately 50 tests. Shipped discretely in a small box with "D.S." as the return address. Overnight delivery Ehrlich’s reagent is recommended for nonfermenting, gram-negative bacilli and for anaerobes.2-4 PRINCIPLE Tryptophanases are intracellular enzymes that mediate the production of indole by hydrolytic activity against the amino acid, tryptophan. Indole combines with dimethyl-aminobenzaldehyde to form a red compound. - I doubt it because the Ehrlich's reagent is basically p–dimethylaminobenzaldehyde (DMAB) dissolved in ethanol and some acid i think.

Federigo Hoglen. 786-457- Ehrlich's reagent or Ehrlich reagent is a reagent that contains p -dimethylaminobenzaldehyde (DMAB) and thus can act as an indicator to presumptively identify indoles and urobilinogen. Several Ehrlich tests use the reagent in a medical test; some are drug tests and others contribute to diagnosis of various diseases or adverse drug reactions.

The test is named after the Nobel Prize winner Paul Ehrlich, who identified this test during the distinction of typhoid from simple diarrhea. Additionally, how do you prepare Ehrlich reagent? The reagent is prepared by dissolving 0.5–2.0 g of p–dimethylaminobenzaldehyde (DMAB) in 50 mL of 95% ethanol and 50 mL of concentrated hydrochloric acid and is best used when fresh. Other alcohols, such as 1-propanol, can also be used as well.

The ehrlich test confirms the presence of indole groups in a sample. LSD , DMT ( ayahuasca ), psilocybin and psilocin (mushrooms), AMT, 5-MeO-DMT , 5-MeO-DIPT, 5-MEO-MIPT, 5-MEO-AMT, 4-ACO-DMT all contain indole groups in their respective molecules and will therefore react with this reagent. Ehrlich, Paul (poul ār`lĭkh), 1854–1915, German bacteriologist.

It helps rule out 2C-x, DOx, NBOMe or different psychedelic phenethylamines. It reacts the same to every indole-based substance, (e.g. 5-HTP), therefore should always be used together with Hofmann test.

Also, is the reagent "good enough" to use alone or should i also purchase marquis(or another)?-thanks in advance. 3 comments.
