Used in pharmaceutical research as a key scaffold for developing kinase inhibitors, particularly in oncology. Its structure supports the design of compounds targeting signaling pathways in cancer cells. Also employed in medicinal chemistry to create analogs with anti-inflammatory and antiviral properties. The carboxylic acid group allows for easy derivatization, enabling the synthesis of amides and esters for structure-activity relationship studies. Commonly found in early-stage drug discovery programs focused on targeted therapies.
