Descripción

2,6-Diaminopyridine is a heterocyclic compound that is used in analytical chemistry as an indicator for the presence of protonated amines. It is prepared by coupling 2,6-diamino-pyridine with 1,3-benzodioxole-5-carboxylic acid. The nitrogen atoms are electron withdrawing groups and form hydrogen bonding interactions with the protonated amine. This type of interaction leads to a phase transition temperature of about 115°C and a high value for electrochemical impedance spectroscopy (EIS) measurements. The reaction mechanism involves the formation of a protonated amine from 2,6-diaminopyridine and 1,3-benzodioxole-5-carboxylic acid followed by proton transfer to yield the corresponding pyridinium salt.
