In order to deepen the understanding of electrosprayionisation collision‐induced dissociation (ESI‐CID) fragmentation reactions of xanthine derivatives for the identification of metabolites using low‐resolution liquid chromatography/massspectrometry (LC/MS) analysis, basic experiments usingcaffeine (1,3,7‐trimethylxanthine) as model compound have been performed.
