Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It plays a crucial role in forming carbon-carbon bonds during the construction of complex heterocyclic systems found in active pharmaceutical ingredients. Its reactivity allows for selective functionalization in multi-step syntheses, especially in drugs targeting tyrosine kinase pathways. Commonly employed in research settings for generating analogs in structure-activity relationship (SAR) studies.
