Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceutical compounds. It acts as a protected form of pyridine N-oxide, where the benzyloxy group at the 4-position shields the oxygen from unwanted reactions during intermediate synthetic steps, enabling selective functionalization of the pyridine ring. This protection can be removed later as needed, facilitating position-specific synthesis. It serves in the development of nitrogen-containing heterocyclic systems, which are common in drug discovery. Its structure allows for efficient modification in reactions requiring precise control, making it valuable in building complex molecules for medicinal chemistry research. Also employed in the synthesis of catalysts and ligands for metal-mediated reactions.
