“…The oxidation-reduction reaction mechanism between Ru(bpy)3 2+ and tertiary amines (Scheme 1) has been investigated by many researchers. [32][33][34] This ECL reaction mechanism has been used for the determination of tertiary aliphatic 35,36 and alicyclic amines, 37 amino acids, 38 and pharmaceutical products, such as erythromycin, 39 clindomycin, 40 and antihistamines. 41 This ECL reagent will, in general, react best with tertiary, then secondary, and finally primary amines.…”
