Used primarily as an intermediate in the synthesis of vitamin K analogs, VK3-OCH3 plays a role in anticoagulant research and development. It is involved in studies related to blood clotting mechanisms and bone metabolism due to its structural similarity to menaquinones. Additionally, it serves as a precursor in the preparation of derivatives for pharmaceutical testing, particularly in evaluating hepatoprotective and anticancer activities. Its methylated form enhances stability and bioavailability in experimental models, making it valuable in medicinal chemistry research.
