Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It plays a role in modifying molecular structures to enhance biological activity, solubility, and target selectivity. Commonly employed in research settings for drug discovery due to its ability to interact with specific enzyme systems. Also utilized in the preparation of anti-inflammatory and antimicrobial agents. Its sulfonyl and carboxylic acid groups allow for further chemical modifications, making it valuable in building complex bioactive molecules.
