Used in organic synthesis for creating complex molecules, particularly in pharmaceutical research where it serves as a building block for developing drugs with potential therapeutic properties. Its structure is valuable in designing compounds that interact with biological targets, such as enzymes or receptors. Additionally, it finds application in material science for developing organic semiconductors or conductive polymers due to its electron-rich thiophene and benzothiophene components. Its unique fused ring system also makes it useful in the study of photophysical properties for optoelectronic devices.
