For professionals in the electronics and material science industries, particularly those focused on Organic Light-Emitting Diodes (OLEDs), the sourcing of high-quality chemical intermediates is paramount. Among these, 1-Bromo-4-iodobenzene (CAS: 589-87-7) stands out as a critical building block. Understanding its properties and reliable supply chains is essential for successful product development and manufacturing.

What is 1-Bromo-4-iodobenzene?

1-Bromo-4-iodobenzene is a dihalogenated aromatic compound featuring a benzene ring with a bromine atom and an iodine atom positioned at opposite (para) locations. Its chemical formula is C6H4BrI, and its molecular weight is approximately 282.90 g/mol. Typically supplied with a purity of 98% or higher, it is characterized by its crystalline powder or needle-like appearance, often ranging in color from white to brown. This compound is valued for its dual halogen functionality, which allows for selective reactivity in various chemical transformations.

The Importance of 1-Bromo-4-iodobenzene in OLEDs

The electronics industry, particularly the rapidly advancing field of OLED technology, relies heavily on precisely synthesized organic molecules. 1-Bromo-4-iodobenzene serves as a key intermediate in the synthesis of advanced materials that form the basis of OLED displays and lighting. Its specific structure and reactivity enable the creation of complex organic frameworks with desired optoelectronic properties, such as efficient light emission and stability. For manufacturers of OLED materials, securing a consistent supply of high-purity 1-Bromo-4-iodobenzene is a strategic imperative.

Applications in Organic Synthesis and Beyond

Beyond its role in OLEDs, 1-Bromo-4-iodobenzene is a versatile reagent in broader organic synthesis. It is frequently employed in palladium-catalyzed cross-coupling reactions, including Suzuki-Miyaura, Stille, Heck, and Sonogashira couplings. These reactions are fundamental for forming new carbon-carbon and carbon-heteroatom bonds, essential for creating complex molecules used in pharmaceuticals, agrochemicals, and fine chemicals. Its ability to undergo selective functionalization makes it an excellent starting material for multi-step synthesis pathways.

Sourcing Considerations for Industry Professionals

When looking to buy 1-Bromo-4-iodobenzene, several factors are crucial for B2B procurement managers and R&D scientists. Firstly, purity is key; a minimum purity of 97% or 98% ensures reliable reaction outcomes and consistent material performance. Secondly, identifying a trustworthy manufacturer or supplier is vital. Companies seek partners who can guarantee stable supply, competitive price points, and adherence to quality standards. For those operating in China, sourcing from a reputable domestic supplier can offer logistical advantages and cost efficiencies.

Many businesses opt to purchase 1-Bromo-4-iodobenzene from specialized chemical suppliers who focus on intermediates for electronics and pharmaceuticals. These suppliers often provide detailed specifications, safety data sheets (SDS), and can accommodate varying order quantities, from grams for research to tons for industrial production. Engaging with a manufacturer that offers technical support and can provide a free sample can further de-risk the procurement process.

In conclusion, for companies involved in OLED material development or intricate organic synthesis, understanding the value and sourcing strategies for 1-Bromo-4-iodobenzene is crucial. Partnering with reliable chemical manufacturers and suppliers in China ensures access to this vital intermediate, driving innovation and production efficiency in the competitive global market.
