Used as a key intermediate in the synthesis of vitamin K analogs and other biologically active naphthoquinone derivatives. It serves in pharmaceutical research for developing anticoagulant agents and studying blood clotting mechanisms. Also employed in the preparation of fluorescent dyes and optical brighteners due to its extended aromatic structure and ability to undergo functionalization at specific ring positions. Its methoxy-naphthyl core makes it valuable in organic electronics and material science for designing charge-transport materials.
