Used in pharmaceutical research as a key intermediate in the synthesis of bioactive molecules, particularly in the development of kinase inhibitors and antitumor agents. Its structure supports binding to enzyme active sites, making it valuable in designing drugs targeting cancer and inflammatory diseases. Also employed in the preparation of fluorescent probes for biochemical assays due to the bromobenzothiazole core’s favorable photophysical properties. Commonly utilized in medicinal chemistry for structure-activity relationship (SAR) studies to optimize drug candidates.
