Used in the synthesis of high-performance polymers, particularly in the development of advanced polyimides and polyamides. These materials exhibit excellent thermal stability, mechanical strength, and chemical resistance, making them suitable for aerospace, microelectronics, and high-temperature filtration applications. Also serves as a building block in organic semiconductors and optoelectronic devices due to its conjugated structure and electron-transport properties. Investigated for use in dye-sensitized solar cells and as a component in corrosion inhibitors for metal protection.
