For chemists and material scientists engaged in the synthesis of advanced organic molecules, a thorough understanding of key intermediates is indispensable. 1-(4-Bromophenyl)-1,2,2-triphenylethylene, identified by its CAS number 34699-28-0, is one such compound, highly valued for its utility in organic electronics and complex chemical synthesis. This article delves into its synthesis pathways and critical properties, offering insights valuable for procurement and R&D professionals.

The synthesis of 1-(4-Bromophenyl)-1,2,2-triphenylethylene often involves multi-step organic reactions, typically starting from readily available precursors like diphenylmethane and substituted benzophenones or related halogenated aromatics. A common route might involve organometallic chemistry, such as lithiation of diphenylmethane followed by reaction with a 4-bromobenzophenone derivative, and subsequent dehydration or elimination steps to form the ethene linkage. These processes require careful control of reaction conditions, including temperature, inert atmosphere, and solvent selection, to achieve high yields and purity.

The resulting compound is typically a crystalline powder, presenting in shades from white to light yellow. A critical parameter for its application, particularly in high-performance materials, is its purity, which is commonly specified at 98% or higher by Gas Chromatography (GC). The melting point is another key identifier, generally falling within the range of 157.0°C to 161.0°C. Its solubility in organic solvents such as toluene facilitates its use in solution-based synthesis and processing.

As a functionalized triarylethylene, this compound's significance is amplified by its potential as a building block. The bromine atom provides a handle for further synthetic transformations, such as Suzuki, Stille, or Sonogashira couplings, allowing for the introduction of diverse functional groups. This capability is crucial for tailoring molecular properties for specific applications, such as tuning the electronic band gap or enhancing charge carrier mobility in organic semiconductors for OLEDs.

For businesses looking to source this chemical, understanding these synthetic aspects and purity specifications is vital. Partnering with experienced manufacturers, especially those based in China known for their robust chemical synthesis capabilities, can ensure a consistent supply of high-quality 1-(4-Bromophenyl)-1,2,2-triphenylethylene. When you buy, always ensure you receive comprehensive technical data, including detailed synthesis routes if available, alongside COAs, to guarantee the material’s suitability for your advanced chemical projects.
