In the intricate world of chemical synthesis, specific intermediate compounds serve as indispensable building blocks for creating advanced materials. One such compound, 9-Phenyl-3-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-yl)-9H-Carbazole, identified by CAS number 1126522-69-7, stands out for its utility in various cutting-edge applications, particularly within the electronics and specialty chemical sectors.

This molecule combines a robust carbazole framework with a phenyl substituent and a boronic acid pinacol ester group. The carbazole core is renowned for its excellent charge-transport properties and thermal stability, making it a favoured component in organic electronic devices. The phenyl group attached to the nitrogen atom of the carbazole can modulate its electronic characteristics and solubility. Crucially, the boronic acid pinacol ester moiety provides a reactive handle for cross-coupling reactions, such as the widely used Suzuki-Miyaura coupling. This reactivity allows chemists to precisely attach the carbazole unit to other molecular fragments, enabling the construction of complex conjugated systems.

The primary application for 9-Phenyl-3-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-yl)-9H-Carbazole lies in the synthesis of materials for Organic Light-Emitting Diodes (OLEDs). Its incorporation into host materials, emissive layers, or charge-transport layers can significantly enhance device efficiency, color purity, and operational lifetime. Beyond OLEDs, this intermediate is also valuable in the research and development of other organic electronic materials, including organic photovoltaics, field-effect transistors, and specialized photocatalysts.

When procuring this compound, attention to its specifications is vital. Typically supplied as a pale yellow powder, its melting point, ranging from 162.0 to 166.0 °C, serves as an important indicator of purity. For optimal performance in demanding applications, a minimum purity of 97% is generally recommended. Buyers should seek out manufacturers who can consistently deliver on these quality parameters.

For those looking to purchase 9-Phenyl-3-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-yl)-9H-Carbazole, engaging with established chemical suppliers, especially those based in China renowned for their expertise in organic synthesis, is a prudent strategy. These manufacturers can often provide competitive pricing, flexible packaging options (from research quantities to bulk industrial supply), and reliable delivery. Obtaining a detailed quote and perhaps a free sample allows for thorough evaluation before making a significant purchase, ensuring that this key organic intermediate meets your project's precise requirements.
