Used in pharmaceutical research as a key intermediate in the synthesis of potent kinase inhibitors, particularly targeting tyrosine kinases involved in cancer cell proliferation. Its structure enables selective binding and high potency in modulating signaling pathways in oncology drug development.

Commonly employed in the preparation of active pharmaceutical ingredients (APIs) for investigational anti-tumor agents, especially in solid tumor models. Also utilized in structure-activity relationship (SAR) studies to optimize bioavailability and target affinity in preclinical candidates.
