Used in the synthesis of chiral terpene derivatives, particularly in the production of fragrances and flavor compounds. Acts as an intermediate in organic reactions where stereochemistry is important, enabling the formation of specific enantiomers in aroma chemicals and pharmaceuticals. Commonly employed in cyclization and coupling reactions to build complex cyclic structures found in natural products. Its reactivity makes it valuable in creating scent molecules for perfumery, especially those mimicking pine, citrus, or herbal notes.
