Used as a key intermediate in the synthesis of kinase inhibitors, particularly in pharmaceuticals targeting cancer. It plays a role in the development of selective inhibitors for proteins involved in cell signaling pathways, such as JAK and FLT3 kinases. Its structure allows for modifications that enhance binding affinity and selectivity, making it valuable in drug discovery for hematological malignancies and inflammatory diseases. Also utilized in research settings to design small molecule therapeutics with improved pharmacokinetic properties.
