Used in pharmaceutical research as an intermediate in the synthesis of biologically active compounds, particularly in the development of kinase inhibitors. Its structure supports binding to enzyme active sites, making it valuable in creating potential treatments for cancer and inflammatory diseases. The compound's sulfonate ester group enhances solubility and reactivity, facilitating further chemical modifications in drug design. It is also employed in structure-activity relationship (SAR) studies to optimize potency and selectivity of new drug candidates.
