The imino ether, 2-(4-Ethoxyphenyl)-acetimidic acid ethyl ester hydrochloride, is prepared by dissolving the 4-substituted benzyl cyanide in a mixture of anhydrous ethanol and chloroform and then saturating this solution with dry hydrogen chloride gas. The reaction between the 2-(β-dialkylaminoalkylamine)-5-nitroaniline and the HCl salt of the ...
Etodesnitazene (also known as desnitroetonitazene, etazen, etazene, and etazone) is a benzimidazole-derived opioid analgesic drug, which was originally developed in the late 1950s alongside etonitazene and a range of related derivatives. [1]
Methylenedioxynitazene (3',4'-Methylenedioxynitazene) is a benzimidazole derivative which has been sold as a designer drug over the internet and presumably has opioid effects. It is an analogue of etonitazene where the benzyl ring is substituted with a 3,4-methylenedioxy ring system rather than an ethoxy group. It was first reported in the UK ...
Benzimidazole is a base: C 6 H 4 N(NH)CH + H + → [C 6 H 4 (NH) 2 CH] + It can also be deprotonated with stronger bases: C 6 H 4 N(NH)CH + LiH → Li [C 6 H 4 N 2 CH] + H 2. The imine can be alkylated and also serves as a ligand in coordination chemistry. The most prominent benzimidazole complex features N-ribosyl-dimethylbenzimidazole, as ...
Butonitazene is a benzimidazole derivative with opioid effects, which has been sold over the internet as a designer drug.It has relatively low potency compared to many related compounds, and has generally been encountered as a component of mixtures with other substances rather than in its pure form.
Etomethazene (5-methyldesnitroetonitazene, 5-methyl etodesnitazene, Eto) is a benzimidazole derivative with opioid effects which has been sold as a designer drug over the internet since 2022, first being definitively identified in Sweden in January 2023.
The van Urk reagent, which uses 0.125 g of p-DMAB, 0.2 mL of ferric chloride solution (25 mg/mL) in 100 mL of 65% sulfuric acid. [ 9 ] [ 10 ] [ 11 ] This is sometimes referred to as the Hofmann reagent or p-DMAB-TS (Test Solution) and gives slightly different colours with different indoles.
