Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its structure allows for functionalization at multiple sites, making it valuable in constructing complex molecules. Commonly employed in the development of fluorescent probes and dyes due to the presence of the benzothiazole moiety, which exhibits favorable photophysical properties. Also utilized in medicinal chemistry for designing bioactive compounds targeting enzymes and receptors, especially in research related to neurodegenerative diseases and cancer.
