For professionals in the chemical and electronics industries, a thorough understanding of a material's properties is fundamental to making informed purchasing decisions. Bis(4-biphenylyl)amine (CAS 102113-98-4) is a prime example of a specialty chemical whose utility is deeply rooted in its specific chemical characteristics. As a leading supplier, NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing comprehensive insights into the materials we offer, enabling our clients to leverage them effectively.

Bis(4-biphenylyl)amine, with the molecular formula C24H19N and a molecular weight of 321.42, is an organic compound belonging to the aromatic amine class. Its structure features a central nitrogen atom bonded to two biphenyl groups, creating an extended π-conjugated system. This structural attribute is directly responsible for its excellent charge transport capabilities, making it highly sought after in the field of organic electronics, particularly for OLED applications. The compound typically presents as a white to off-white crystalline powder, indicating a solid state at room temperature.

A critical property that dictates its performance in electronic devices is its purity. As a supplier, we emphasize that Bis(4-biphenylyl)amine is generally available with a minimum purity of 98.0% or, more commonly, ≥99.0% (GC or HPLC). This high degree of purity is essential for minimizing charge trapping and exciton quenching, which are detrimental to OLED efficiency and lifespan. When you decide to buy Bis(4-biphenylyl)amine, always verify the purity specifications and the analytical methods used by the manufacturer.

Thermal properties are also key considerations for R&D scientists and process engineers. Bis(4-biphenylyl)amine exhibits a high melting point, typically around 209°C, and a high boiling point (predicted around 507°C). This thermal stability is advantageous for applications that may involve vacuum deposition processes or operation at elevated temperatures, contributing to the overall robustness of the electronic devices.

Furthermore, understanding its solubility characteristics is important for formulation and processing. While slightly soluble in solvents like acetonitrile, chloroform, and DMSO, its processing often involves specialized deposition techniques. For procurement managers and R&D teams, a clear understanding of these chemical properties – from molecular structure to thermal stability and purity levels – is crucial. This knowledge empowers better material selection and ensures that the Bis(4-biphenylyl)amine purchased from suppliers like NINGBO INNO PHARMCHEM CO.,LTD. will meet the demanding requirements of advanced electronic material development.
