The world of advanced materials is constantly evolving, driven by innovations in sectors like electronics and displays. Central to these advancements are specialized chemical intermediates, and 4-ethyl-4'-iodobiphenyl (CAS 17078-76-1) plays a vital role in the production of high-performance liquid crystals. This article examines why this compound is so significant and offers guidance for professionals looking to buy it from reliable sources.

The Functional Role of 4-Ethyl-4'-iodobiphenyl

4-Ethyl-4'-iodobiphenyl is a carefully engineered molecule designed for specific synthetic purposes. Its biphenyl core provides a rigid structure, while the ethyl group and iodine atom offer sites for further chemical reactions. As a liquid crystal intermediate, its precise molecular configuration contributes to the mesogenic properties required for effective display technology. The iodine atom, in particular, is a reactive handle that allows for the facile creation of more complex molecules through cross-coupling reactions, a cornerstone of modern organic synthesis. This makes it an indispensable component for chemists formulating new liquid crystal materials that offer enhanced clarity, faster response times, and wider viewing angles.

Key Properties Relevant to Industrial Use

For manufacturers, the properties of 4-ethyl-4'-iodobiphenyl are critical. It is commonly supplied as a white or off-white solid, indicating good purity and stability. The purity level, typically above 99.5%, is paramount for ensuring predictable results in sensitive synthesis processes. Its relatively high boiling point (347.4°C at 760 mmHg) suggests thermal stability, which is advantageous in many industrial reaction conditions. The flash point (157.5°C) is also an important safety metric for handling and storage. These characteristics collectively make it a dependable choice for those who need to buy this chemical for large-scale production or complex research projects.

Where to Buy: Choosing a Quality Manufacturer

Procuring specialty chemicals like 4-ethyl-4'-iodobiphenyl requires careful supplier selection. Many buyers turn to China for its robust fine chemical manufacturing sector, which often offers competitive pricing and ample production capacity. When seeking a 4-ethyl-4'-iodobiphenyl manufacturer, it is essential to prioritize those who provide detailed technical specifications, Certificates of Analysis (CoAs), and a commitment to consistent quality. Look for suppliers with a proven track record in producing intermediates for the electronics and display industries. Engaging directly with manufacturers for quotes can ensure the best value and direct communication regarding product requirements, such as custom packaging in 20 kg drums.

Conclusion: Driving Innovation with Quality Intermediates

4-Ethyl-4'-iodobiphenyl is a fundamental building block that empowers innovation in liquid crystal technology. Its carefully designed molecular structure and high purity make it essential for creating advanced display materials. By strategically sourcing this intermediate from reputable manufacturers, companies can ensure the quality and performance of their products, driving technological progress in the competitive global market.
