Used in organic synthesis as a key intermediate for the development of complex molecules, particularly in pharmaceutical research. Its structure is valuable for constructing isoquinoline derivatives, which are often explored for their biological activities. Applied in the study of potential therapeutic agents, including anti-cancer, anti-inflammatory, and antimicrobial compounds. Also serves as a building block in the synthesis of heterocyclic compounds for material science applications. Its unique properties make it useful in designing molecules with specific electronic or structural characteristics.
