Used as a key intermediate in the synthesis of fluorescent dyes and optoelectronic materials due to its extended conjugated system and halogen substitution. The compound serves in Suzuki and Heck coupling reactions to build complex heterocyclic structures for use in organic semiconductors and sensor technologies. Its coumarin backbone with bromo and chloro groups enables selective functionalization for developing bioactive molecules, including potential antimicrobial and anticancer agents. Also employed in photochemical studies for its light-absorbing properties, making it suitable for UV-absorber formulations and fluorescent probes in imaging applications.
