For professionals in the chemical and materials industries, understanding the sourcing and application of key intermediates is crucial for project success. This guide focuses on 4,4''-Dibromo-p-terphenyl (CAS 17788-94-2), a vital compound for advanced research and manufacturing, and provides insights on how to best purchase it, particularly from manufacturers in China.

4,4''-Dibromo-p-terphenyl is characterized by its terphenyl backbone and two bromine atoms, making it an excellent substrate for palladium-catalyzed cross-coupling reactions. These reactions are instrumental in building complex organic molecules with tailored electronic and optical properties. Its high melting point (around 315 °C) signifies excellent thermal stability, a desirable trait for many high-performance applications.

The primary demand for 4,4''-Dibromo-p-terphenyl stems from its extensive use in the electronics sector, particularly in the synthesis of OLED materials. Researchers utilize it to construct molecules that efficiently transport charge or emit light, contributing to the development of brighter, more energy-efficient displays. Beyond OLEDs, it serves as a building block for liquid crystals and specialty polymers, where its rigid structure and reactivity are highly valued.

When considering a purchase, it is essential to buy from reputable suppliers who can guarantee product purity and consistency. Many leading manufacturers in China specialize in producing high-grade organic intermediates like 4,4''-Dibromo-p-terphenyl, often achieving purity levels of 99% or more. These suppliers are equipped to handle orders ranging from laboratory-scale quantities for R&D to bulk volumes for industrial production.

To make an informed purchase, prospective buyers should:

  • Verify the purity and analytical data (e.g., HPLC, NMR) provided by the manufacturer.
  • Inquire about packaging options suitable for their needs (e.g., 25g, 1kg, bulk drums).
  • Compare pricing from multiple suppliers to ensure competitive rates.
  • Check lead times for delivery, especially for larger orders.
  • Request Safety Data Sheets (SDS) for safe handling and storage procedures.

By diligently researching and selecting a reliable manufacturer or supplier, particularly within China's robust chemical industry, you can ensure access to high-quality 4,4''-Dibromo-p-terphenyl at favorable pricing. This strategic sourcing approach is key to facilitating your advancements in materials science and electronics manufacturing.
