Three new NBOH compounds—25B-NBOH, 25C-NBOH, and 25E-NBOH—were identified and structurally characterized in blotter papers seized by police in Brazil between 2017 and 2018. The substances were extracted and analyzed using infrared spectroscopy, gas and liquid chromatography–mass spectrometry, and nuclear magnetic resonance spectroscopy. This is the first detailed report of these substances in seized samples. NBOHs are not controlled under United Nations conventions and have become the main hallucinogenic drug in the region since 2014. They are thermolabile under gas chromatography, requiring alternative analytical methods to avoid misidentification. Knowledge about their toxicology remains limited.
