Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of selective estrogen receptor modulators (SERMs). It contributes to the structural framework that enables modulation of estrogen receptors, making it valuable in treatments for hormone-related conditions such as breast cancer and osteoporosis. Its fluorinated aromatic system enhances metabolic stability and binding affinity, which improves the efficacy and pharmacokinetic profile of the final drug compounds. Also employed in research settings for designing new bioactive molecules due to its favorable physicochemical properties and ability to cross cell membranes.
