Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to the presence of the indazole core, which is known for its biological activity. Commonly employed in the preparation of active pharmaceutical ingredients (APIs) targeting tyrosine kinases and other signaling enzymes involved in tumor growth. Also utilized in research settings for structure-activity relationship (SAR) studies to optimize drug candidates. Its ester functionality allows for easy modification, enabling the introduction of various side chains to enhance potency and selectivity.
