4,5,9,10-Tetrabromoisochromeno[6,5,4-def]isochromene-1,3,6,8-tetraone(CAT: L032252) is a highly brominated, polycyclic aromatic compound featuring a fused isochromene system with four reactive ketone groups. Its rigid, planar structure and electron-deficient nature make it a valuable intermediate in the synthesis of functional dyes, pigments, and organic semiconductors. The multiple bromine atoms offer versatile sites for further functionalization through cross-coupling reactions (e.g., Suzuki, Stille), facilitating the development of advanced π-conjugated systems. This compound is particularly suited for applications in optoelectronics, organic photovoltaics, and material science, where high thermal stability, extended conjugation, and tunable electronic properties are essential for performance optimization.
