Primarily used as a building block in organic synthesis, particularly in the development of advanced materials and pharmaceuticals. It serves as a key intermediate in the production of dyes, pigments, and photoactive compounds due to its unique brominated structure. Additionally, it is utilized in the creation of light-sensitive agents for imaging technologies and photoresists in semiconductor manufacturing. Its tetrahedral isoindoline core also makes it valuable in designing molecular probes and sensors for detecting specific chemical or biological targets.
