Challenges in Drug Surveillance: Strengthening the Analysis of New Psychoactive Substances by Harmonizing Drug Checking Services in Proficiency Testing.
mainly unidentified compounds, presumably due to no up-to-date libraries, and/ or confusion between structural isomers, such as 3- and 4-chloroethcathinone, or structural analogs, such as MIPLA ...
Analytical characterization of "etonitazepyne," a new pyrrolidinyl-containing 2-benzylbenzimidazole opioid sold online.
regio-isomer was confirmed using H NMR spectroscopy, resulting in the unambiguous identification of etonitazepyne. Health Topics: Illicit drugs Drogues illégales Illegale drugs Service: Information sanitaire ...
Report on a New Opioid NPS: Chemical and In Vitro Functional Characterization of a Structural Isomer of the MT-45 Derivative Diphenpipenol.
obtained was actually a diphenpipenol structural isomer, (2-[4-(2-methoxyphenyl)piperazin-1-yl]-1,2-diphenylethanol). Liquid chromatography time-of-flight mass spectrometry identified an exact mass for the ...
Enantiomeric fraction of hexabromocyclododecanes in foodstuff from the Belgian market
enantiomeric fractions of the same samples. None of the samples could be considered as racemic for the α-isomer suggesting that foodstuff contamination occurred prior to death of the corresponding producing ...

Scientific Opinion of the EFSA Panel on Plant Protection Products and their Residues (PPR) on Evaluation of the toxicological relevance of pesticide metabolites for dietary risk assessment
proposed. The opinion also proposes how the risk assessment of pesticidemetabolites that are stereoisomers should be addressed due to isomer ratio changes reflected in thecomposition of metabolites. The ...
