Used as a key intermediate in the synthesis of kinase inhibitors, particularly in anticancer drug development. Shows activity in targeting tyrosine kinase pathways involved in tumor growth and cell proliferation. Employed in research for potential treatments of solid tumors and hematological malignancies. Also utilized in structure-activity relationship (SAR) studies to optimize potency and selectivity of indole-based pyrimidine derivatives. Suitable for in vitro assays and preclinical evaluation in oncology-focused drug discovery programs.
