Used as a key intermediate in organic synthesis, particularly in the preparation of seven-membered ring compounds. Its structure allows for facile functionalization at the alpha position to the ketone, making it valuable in the synthesis of pharmaceuticals and natural products. Commonly employed in cyclization reactions and carbon-chain elongation processes. Also utilized in the development of fragrances due to its ability to form macrocyclic musks when further modified. Suitable for research in heterocyclic chemistry and ring-expansion methodologies.
