Used in pharmaceutical research as an intermediate for synthesizing kinase inhibitors, particularly in the development of anticancer agents. It plays a role in the production of small molecule drugs targeting tyrosine kinase pathways involved in tumor growth and cell proliferation. Its structure supports binding selectivity, making it valuable in optimizing drug candidates for improved efficacy and reduced side effects. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to modulate biological activity in peptide-like frameworks.
