Trace amines are endogenous compounds, typified by 2-phenylethylamine (PE) and p-tyramine (TA), found in the vertebrate central nervous system. Although synthesized in pre-synaptic terminals, trace amines do not appear to act as neurotransmitters, but rather modulate responsivity to co-existing neurotransmitters.

In this study, a novel pre-column excimer fluorescence derivatization reagent, 2-chloro-4-methoxy-6-(4-(pyren-4-yl)butoxy)-1,3,5-triazine (CMPT), was developed for polyamines, specifically histamine. By CMPT derivatization, the polyamines, histamine and tyramine were converted to polypyrene derivatives, and emitted intra-molecular excimer fluorescence at 475nm. This could
