General description

2-Aminopyridine is a basic building block of several heterocyclic compounds and Schiff bases.

Application

2-Aminopyridine (2AP) is a derivatizing agent which can be used as a fluorescent label for oligosaccharide detection, chromatographic separation, fluorometric or mass spectrometric analysis.
2AP and its derivatives are good candidates for antimicrobial, anticorrosion and molecular sensing applications.
