The cathinone eutylone was first detected in Europe in 2014 and later reported in the US in 2018. Eutylone has since become one of the most prevalent synthetic stimulants identified in forensic casework, and new substituted cathinones continue to emerge on the NPS market. Inconsistent and unstandardized naming of designer drugs in the cathinone structural class presents unique challenges to various stakeholders tasked with the identification of these drugs. In an effort towards clearer communication within the field, this poster describes the common naming conventions used in literature and establishes a standardized approach to naming modifications of the cathinone core structure. Common cathinone fragments, tips for mass spectrometry interpretation, and common substitutions are also presented to help the forensic community decipher the structure of new designer cathinones.  

In this laboratory guide for drug identification and naming, we cover:

• Common Substitutions
• Mass Spectrum of Eutylone and Tips for Interpretation
• Common Mass Spec Fragments
• A Standardized Alkylphenone Naming System
• Other Common Naming Conventions
