In the realm of advanced materials for electronic applications, 4-Cyano-4'-pentylbiphenyl (5CB) holds a prominent position, particularly within the liquid crystal display (LCD) industry. This organic chemical compound, identified by CAS No. 40817-08-1, is a key nematic liquid crystal, prized for its unique characteristics that enable the functionality of modern displays. Understanding its properties is essential for anyone looking to buy 5CB.

5CB is characterized by its chemical formula C18H19N and a molecular weight of 249.35 g/mol. Its appearance is typically a white crystalline solid. The material exhibits a well-defined nematic phase range, usually between 22°C and 35°C, meaning it functions effectively within a common operational temperature window for electronic devices. Its key strengths lie in its electro-optical properties, including a suitable birefringence (Δn≈0.18) and a positive dielectric anisotropy (Δε≈+10). These attributes are critical for its role in controlling light polarization in LCDs.

The primary application for 5CB is in the manufacturing of LCDs, where it serves as a fundamental component in Twisted Nematic (TN) displays. These displays are found in a vast array of products, from simple digital watches and calculators to complex industrial control panels and early generations of computer monitors. Its fast response time and good chemical stability contribute to the longevity and reliability of these devices. When sourcing for these applications, many companies seek a reliable 5CB manufacturer to ensure consistent supply and quality.

For businesses operating in the electronics sector, securing a dependable supply of 5CB is crucial. Reputable 5CB suppliers, particularly those based in China, offer high-purity grades of the material, often exceeding 99.9%. This level of purity is vital for optimal device performance and consistency. When considering where to purchase 5CB, looking for manufacturers with a strong track record in specialty chemicals and a commitment to quality assurance is paramount. Companies like NINGBO INNO PHARMCHEM CO.,LTD. are dedicated to providing these essential materials to global markets, ensuring that product development and manufacturing processes are supported by reliable chemical sourcing.
