Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its ethynyl and cyclopropyl groups enable selective modifications that enhance binding affinity to target proteins. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its rigid structure and ability to improve metabolic stability in drug candidates. Also utilized in agrochemical research for designing bioactive molecules with improved potency and selectivity.
