Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective modification, making it valuable in creating bioactive molecules. Commonly employed in medicinal chemistry research to build indazole-based drug candidates targeting inflammation, neurological disorders, and oncology. Also utilized in agrochemical research for designing novel active ingredients. Its aldehyde functional group enables easy coupling with amines or hydrazines to form imines or hydrazones, facilitating rapid compound library generation for screening.
