Used primarily as a building block in medicinal chemistry, this compound enables the incorporation of the bicyclo[1.1.1]pentane (BCP) motif into target molecules. The BCP group serves as a bioisostere for phenyl rings and alkynes, improving pharmacokinetic properties such as metabolic stability and solubility. The iodine atom allows for further functionalization via cross-coupling reactions, making it valuable in drug discovery for creating novel analogs. Its rigid structure also helps in modulating the conformation of drug candidates, enhancing target selectivity and potency.
