Product Description:

4-Bromo-3-fluorotoluene is an organic compound featuring both bromine and fluorine substituents on a toluene backbone. It is a halogenated aromatic building block with the molecular formula C7H6BrF. This compound is a colorless to pale yellow liquid at room temperature. Its primary application is as a versatile intermediate in organic synthesis, particularly in the pharmaceutical and materials science industries. The presence of both bromine and fluorine atoms makes it a valuable precursor for cross-coupling reactions (e.g., Suzuki, Stille) and for introducing fluorinated aromatic motifs. It is notably used in the synthesis of advanced materials, including organic light-emitting diode (OLED) materials and liquid crystals, where fluorinated aromatic units are crucial for tuning electronic properties, stability, and charge transport. As a halogenated compound, it requires careful handling. It is typically stored under inert conditions and is considered an irritant to skin, eyes, and the respiratory system. Its synthesis and use are common in research and development for creating complex functional molecules.
