In the realm of advanced chemical synthesis for optoelectronic applications, detailed knowledge of specific compounds is essential. Biphenyl-4-yl-(4-carbazol-9-yl-phenyl)-amine, identified by CAS number 1210470-43-1 and often abbreviated as CPBPA, is one such compound gaining significant attention. This article provides a chemical profile for procurement managers and R&D scientists interested in understanding its characteristics and applications, particularly within the burgeoning OLED industry.

CPBPA is characterized by its molecular formula C30H22N2 and a molecular weight of 410.51 g/mol. Its typical appearance is a white powder, signifying its processed state after synthesis. For critical applications like OLEDs, the purity level is paramount, with manufacturers typically offering it at ≥98.0% assay. This high purity is fundamental to ensuring the stability and performance of organic electronic devices, as even trace impurities can lead to performance degradation.

The chemical structure of CPBPA, featuring linked biphenyl and carbazole groups, imbues it with favorable electronic properties. These include good charge carrier mobility and high thermal stability, making it a valuable intermediate for synthesizing host materials in OLED devices. Host materials are crucial for efficiently transferring energy to emissive dopants, thereby improving the overall brightness and efficiency of the light emission.

When considering a manufacturer or supplier for CPBPA, it's vital to assess their manufacturing capabilities, quality control processes, and ability to provide consistent supply. For many companies, sourcing specialty chemicals from China offers a balance of quality and competitive price. Buyers should always request detailed technical data sheets and certificates of analysis to verify product specifications before making a purchase decision.

The primary application for CPBPA is as an intermediate in the synthesis of materials used in OLED displays and lighting. Its specific properties make it suitable for various roles within the complex multi-layered structure of an OLED. For those looking to buy CPBPA for research or industrial production, understanding these applications and the importance of purity will guide your selection of a reliable partner.
