Used primarily as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective modification, making it valuable in creating active pharmaceutical ingredients (APIs) targeting specific signaling pathways. It is also employed in research settings to develop analogs for structure-activity relationship (SAR) studies. Due to its functional groups, it participates in coupling reactions, ether formations, and acylation processes during drug design. Its chloro and hydroxyl groups provide sites for further chemical transformations, enhancing its utility in medicinal chemistry.
