Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for targeted cancer therapies. Its structure supports selective binding to enzyme active sites, making it valuable in drug discovery. It is also employed in the preparation of bioactive molecules with antiviral and anti-inflammatory properties. Due to its sulfonyl and heteroaromatic functionalities, it serves as a building block in medicinal chemistry for constructing complex molecules with enhanced metabolic stability and potency.
