Used as a key intermediate in the synthesis of anticoagulant rodenticides, particularly in the production of second-generation compounds like bromadiolone and difenacoum. Its structure allows for high biological activity in inhibiting vitamin K epoxide reductase, leading to fatal hemorrhaging in rodents. Due to its lipophilic nature, it is effective in bait formulations that resist environmental degradation. Also employed in analytical standards for toxicological screening in cases of poisoning.
