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 its ability to form stable heterocyclic structures that interact with biological targets. Commonly employed in the preparation of active pharmaceutical ingredients (APIs) where the indazole core enhances binding affinity and selectivity. Also utilized in research settings for designing new bioactive molecules with potential anti-inflammatory, antiviral, or neuroprotective properties. Its functional groups allow for easy modification, making it valuable in structure-activity relationship (SAR) studies.
