Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of selective estrogen receptor modulators (SERMs). Its cyclopropane structure with a trans configuration provides conformational rigidity, enhancing binding selectivity to hormone receptors. Commonly employed in research settings for optimizing drug candidates targeting breast cancer and osteoporosis. Also utilized in asymmetric synthesis due to its chiral cyclopropane core, enabling the construction of complex bioactive molecules.
