Understanding the fundamental chemistry of organic intermediates is key to unlocking their full potential in various applications. 1-bromo-3-(4-phenylphenyl)benzene, bearing the CAS number 1762-87-4, is a compound whose structure and properties make it a vital component in advanced chemical synthesis, particularly for OLED materials.

NINGBO INNO PHARMCHEM CO.,LTD. offers this compound, presenting it as a pale yellow to white powder with a guaranteed purity of 97% minimum. Its molecular formula, C18H13Br, reveals a structure comprising three phenyl rings (a terphenyl system) with a bromine atom attached to one of the terminal rings and a phenyl substituent on the central ring. This specific arrangement of aromatic rings provides rigidity and extended conjugation, properties highly desirable in organic electronic materials.

The presence of the bromine atom is significant for synthetic chemists. It serves as a reactive functional group, readily participating in various cross-coupling reactions, such as Suzuki, Heck, or Sonogashira couplings. These reactions allow for the facile introduction of other functional groups or molecular fragments, enabling the construction of complex conjugated systems essential for OLED emitters, hole-transporting layers, and electron-transporting layers.

The synthesis of 1-bromo-3-(4-phenylphenyl)benzene typically involves established organic synthesis methodologies, often employing palladium-catalyzed cross-coupling reactions to assemble the terphenyl core, followed by bromination at the desired position. NINGBO INNO PHARMCHEM CO.,LTD. likely employs optimized synthetic routes to ensure high yield and purity, meeting the demanding specifications of their clientele in the electronics and specialty chemical sectors.

The molecular weight of 309.2g/mol and its physical state as a powder are practical considerations for handling and storage. Preserving its integrity by storing it in well-closed, light-resistant, and airtight containers in a cool, dry place, as recommended, is crucial for maintaining its high purity and reactivity over time. The compound's role as an OLED intermediate and its utility in agrochemical synthesis further emphasize the importance of understanding its detailed chemistry for successful product development.
