Product Description:

4-Formylbiphenyl is an organic compound featuring a biphenyl core substituted with a formyl group at the para position. It is a white to off-white crystalline powder with a molecular formula of C13H10O. This compound serves as a crucial aromatic aldehyde building block in organic synthesis. Its primary and most significant application is in the field of materials chemistry, particularly as a key precursor for the synthesis of advanced organic electronic materials. It is extensively used to construct various organic light-emitting diode (OLED) materials, including host materials, electron transport materials (ETMs), and hole transport materials (HTMs). The biphenyl moiety provides rigidity and conjugation, while the aldehyde group allows for further functionalization via condensation reactions (e.g., to form Schiff bases or via Suzuki coupling after conversion to a boronic ester) to create larger π-conjugated systems essential for optoelectronic properties. Due to its well-defined structure and reactivity, it is also a valuable and common synthetic intermediate in academic and industrial research laboratories for constructing complex organic molecules beyond materials science, making it a standard item in the catalog of organic synthesis building blocks.
