This chemical is primarily used in organic synthesis as a key intermediate for the preparation of various anthracene derivatives. Its sulfonyl chloride group makes it highly reactive, enabling it to participate in coupling reactions to form sulfonamides or sulfonate esters, which are valuable in the development of dyes, pigments, and fluorescent materials. Additionally, it finds application in the creation of photoactive compounds due to the anthracene core, which is known for its photophysical properties. It is also utilized in research for designing molecules with potential applications in optoelectronics and sensors.
