Application

4-Hydroxymethyl-4′-methyl-2,2′-bipyridyl is widely used as a precursor for designing transition metal catalysts in asymmetric synthesis. Its bipyridyl core serves as a chelating agent for ruthenium and iridium complexes in photochemical applications. Researchers also employ it to construct functionalized MOFs for gas storage and separation. The hydroxymethyl group allows further derivatization for polymer-supported catalysts or fluorescent probes.
