Polyamine and tyramine analysis method using pyrene containing fluorescence derivatization reagent and excimer fluorescence

An amine analysis method of analyzing a polyamine having a plurality of amino groups in a same molecule or tyramine, the method comprising:

• preparing a sample containing the polyamine or tyramine;
• adding a fluorescence derivatization reagent having a pyrene group to the sample;
• analyzing the polyamine or tyramine on a basis of a measurement result of intensity of excimer fluorescence emitted as a result of derivatization of the polyamine or tyramine with the fluorescence derivatization reagent,
• wherein the fluorescence derivatization reagent comprises a compound represented by the general formula (1):
• wherein X represents a halogen element, R1 represents an alkyl group, and R2 represents an alkyl chain;
• and wherein the fluorescence derivatization reagent is dissolved in a solvent.
