Used primarily as a key intermediate in the synthesis of biologically active compounds, particularly in the development of pharmaceuticals. Its cyclopropyl structure with a hydroxyl group enables selective functionalization, making it valuable in constructing chiral building blocks for drug design. It is often employed in the preparation of analogs for central nervous system agents and anti-inflammatory compounds. The presence of the o-tolyl group enhances steric and electronic properties useful in asymmetric synthesis. Its trans configuration is critical for achieving desired stereochemistry in final active molecules.
