Used primarily as an intermediate in the synthesis of dyes and pigments, especially in the production of cyanine dyes for photographic materials. It also serves as a building block in the development of pharmaceuticals, including agents with potential antimicrobial and anti-inflammatory properties. Its derivatives are explored in agrochemicals for crop protection due to their bioactive characteristics. Additionally, it finds use in the preparation of fluorescent probes and sensors in analytical chemistry, benefiting from the inherent stability and electronic properties of the benzothiazole core.
