Used as a key intermediate in the synthesis of anticoagulant rodenticides, particularly in the production of second-generation compounds like brodifacoum and difenacoum. It contributes to the biological activity of these agents by enhancing their ability to inhibit vitamin K epoxide reductase, leading to disruption of blood clotting in target pests. Its structure allows for high potency and prolonged action, making it effective in controlling resistant rodent populations. Also investigated for potential applications in medicinal chemistry due to its naphthofuran scaffold, which shows promise in drug development for anti-inflammatory and anticancer agents.
