Used in pharmaceutical synthesis, particularly as an intermediate in the production of kinase inhibitors and anti-cancer agents. Commonly found in compounds targeting tyrosine kinases, which play key roles in tumor growth and progression. Also serves as a building block in the development of neuroprotective and anti-inflammatory drugs. Its structure is frequently modified to enhance binding affinity and selectivity in drug candidates. Widely utilized in research for designing biologically active molecules due to its presence in natural products and medicinal agents.
