Used as an intermediate in the synthesis of biologically active compounds, particularly in the development of enzyme inhibitors. Its structure supports binding to specific protein targets, making it valuable in medicinal chemistry for designing drugs targeting inflammatory and neurodegenerative diseases. Also employed in research settings to develop fluorescent probes due to the nitrobenzothiazole moiety, which can be modified for detection in cellular imaging. Commonly applied in structure-activity relationship (SAR) studies to optimize potency and selectivity of drug candidates.
