Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for targeted cancer therapies. It serves as a building block in the development of small molecule drugs that modulate signaling pathways involved in tumor growth and inflammation. Its structure supports binding to ATP sites in kinases, making it valuable in designing inhibitors for proteins like JAK or TYK2. Also explored in medicinal chemistry for optimizing drug candidates with improved selectivity and metabolic stability.
