In the competitive landscape of advanced display technology, the quality of raw materials directly dictates the performance of the final product. For manufacturers specializing in liquid crystal displays (LCDs), sourcing high-purity intermediates is paramount. Among these crucial compounds is 4-ethyl-4'-iodobiphenyl (CAS 17078-76-1). This article aims to guide procurement managers and R&D scientists in understanding the significance of this chemical and how to effectively buy it from reputable suppliers.

Understanding 4-Ethyl-4'-iodobiphenyl's Role

4-Ethyl-4'-iodobiphenyl is a complex organic molecule belonging to the biphenyl family. Its specific structure, C14H13I, and a molecular weight of approximately 308.16 g/mol, equip it with properties essential for the synthesis of liquid crystal molecules. These liquid crystals, when manipulated by electric fields, are what enable the visual displays in everything from smartphones and televisions to sophisticated industrial monitors. The presence of the iodine atom facilitates further chemical modifications, allowing chemists to fine-tune the optical and physical characteristics of the resulting liquid crystal materials. For anyone looking to buy this crucial component, understanding its function as a key liquid crystal intermediate is the first step.

Key Properties for Manufacturers

When considering a purchase, manufacturers prioritize specific properties. 4-Ethyl-4'-iodobiphenyl is typically supplied as a white or off-white solid. Its high purity, often exceeding 99.5%, is critical. Impurities can lead to reduced performance, inconsistent color, or shorter operational lifespans in the final LCD product. Furthermore, its physical and chemical properties, such as a stable boiling point of around 347.4°C at 760 mmHg, ensure it can withstand the demanding conditions often encountered in large-scale chemical synthesis. The flash point of 157.5°C also provides an important safety consideration for handling and storage. These attributes make it a reliable building block for chemical engineers and product formulators.

Sourcing Strategies: Finding a Reliable Supplier in China

For many global manufacturers, China represents a significant hub for fine chemical production. When seeking a 4-ethyl-4'-iodobiphenyl supplier in China, it is essential to partner with manufacturers who demonstrate stringent quality control and a proven track record. Look for suppliers who can provide detailed Certificates of Analysis (CoA) confirming the purity and specifications of the product. Furthermore, understanding their production capacity and lead times is vital for ensuring a stable supply chain. Many established manufacturers also offer flexible packaging options, such as 20 kg drums, to accommodate different order sizes. Engaging directly with a manufacturer for a quote can often provide the best pricing and direct technical support.

Ensuring Quality and Cost-Effectiveness

To achieve cost-effectiveness without compromising quality, it is advisable to buy 4-ethyl-4'-iodobiphenyl in bulk quantities directly from a reputable manufacturer. This approach not only secures a more favorable price but also minimizes the risk associated with intermediaries. By carefully vetting potential suppliers and understanding the critical specifications, companies can ensure they are obtaining a high-quality liquid crystal intermediate that contributes to the superior performance of their end products. For those requiring this compound for research or industrial applications, reaching out to known specialty chemical producers in China is a wise strategy.
