Product Description:

3,5-Difluorobenzaldehyde is an organic compound characterized by a benzaldehyde core substituted with two fluorine atoms at the meta positions. It is a colorless to pale yellow liquid or low-melting solid with a molecular formula of C7H4F2O. This compound is a key fluorinated aromatic building block in advanced material synthesis. Its primary and significant application is in the field of organic electronics, particularly as a precursor for the synthesis of organic light-emitting diode (OLED) materials, liquid crystal (LC) compounds, and other functional organic semiconductors. The electron-withdrawing fluorine atoms enhance the thermal stability, electron affinity, and overall performance of the resulting materials. It is also used in pharmaceutical and agrochemical research to introduce the difluorophenyl moiety into target molecules. 3,5-Difluorobenzaldehyde should be handled with care as it is an irritant to the skin, eyes, and respiratory system. It is typically stored under inert conditions to prevent oxidation.
