Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antipsychotic and antihistamine drugs. It serves as a building block in organic reactions due to its stable heterocyclic structure, enabling the formation of more complex molecules. Additionally, it exhibits electrical properties and electron transfer capabilities, making it suitable for organic electronics applications such as organic light-emitting diodes (OLEDs) and organic solar cells. It is also employed in research for studying electron transfer processes, photochemistry, and photocatalysis, as well as a component in dye-sensitized solar cells, due to its oxidation stability and efficient electron-donating properties.
