Used in pharmaceutical research as an intermediate for synthesizing kinase inhibitors, particularly in the development of anticancer agents. It plays a role in modulating cell signaling pathways by targeting specific enzymes involved in tumor growth and proliferation. Due to its functional groups and structural features, it enables conjugation and linker strategies in prodrug design and targeted drug delivery systems. Also explored in the synthesis of antibody-drug conjugates (ADCs) for improved selectivity and efficacy in cancer therapy.
