Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in the preparation of active pharmaceutical ingredients (APIs) targeting tyrosine kinases and other signaling proteins involved in tumor growth. Its structure allows for selective modification, making it valuable in medicinal chemistry for optimizing drug potency and selectivity. Also employed in research settings for designing new bioactive molecules with potential antiviral or anti-inflammatory properties.
