Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. Its structure supports the creation of biologically active molecules with high selectivity. Commonly employed in medicinal chemistry for modifying drug candidates to improve metabolic stability and binding affinity. Also utilized in agrochemical research for designing new active ingredients with enhanced efficacy. Suitable for use in late-stage functionalization due to its reactive ester group and polar sulfonyl moiety.
