Application

2,6-Diamino-3,5-difluoropyridine serves as a key intermediate in the synthesis of fluorinated pharmaceuticals, particularly for kinase inhibitors and antiviral agents. Its electron-deficient pyridine core facilitates Suzuki-Miyaura and Buchwald-Hartwig couplings in medicinal chemistry. Researchers also utilize it to construct fluorinated ligands for catalysis and as a precursor for functionalized pyridine scaffolds in material science. The compound’s bifunctional reactivity (amino + fluorine) enables diverse derivatization strategies.
