In the fast-paced world of electronic materials, securing a dependable supply of high-quality intermediates is paramount for innovation and consistent production. For companies developing cutting-edge OLED technology, sourcing key compounds like 4'-Bromo-N,N-diphenyl-4-biphenylamine (CAS 202831-65-0) requires a strategic approach to supplier selection.

Understanding the Product: 4'-Bromo-N,N-diphenyl-4-biphenylamine

This chemical, with its molecular formula C24H18BrN and CAS number 202831-65-0, is a vital building block in the synthesis of advanced OLED materials. It typically presents as a white powder, with a minimum purity of 97%. Its specific chemical structure, featuring a biphenyl core with a diphenylamine substituent and a bromine atom, makes it highly valuable for creating charge-transporting and emissive layers in OLED devices. Its boiling point of approximately 518.2±33.0 °C at 760 mmHg and density of 1.3±0.1 g/cm³ are important parameters for chemical engineers and formulators.

Key Considerations When Selecting a Supplier

For procurement managers and R&D scientists, choosing the right supplier is crucial. Several factors should guide your decision when looking to buy 4'-Bromo-N,N-diphenyl-4-biphenylamine:

  • Quality and Purity: This is non-negotiable. The supplier must consistently provide material that meets the specified purity levels (e.g., 97% min). Look for suppliers who provide comprehensive Certificates of Analysis (CoA) for each batch.
  • Manufacturing Capability: An established manufacturer, particularly one with significant production capacity, can offer more competitive pricing and ensure a stable supply, especially for larger orders. Geographical location, such as China, often provides access to efficient manufacturing networks.
  • Technical Support and Customer Service: A responsive supplier offering technical assistance can be invaluable. This includes help with product inquiries, logistical support, and troubleshooting.
  • Pricing and Payment Terms: Obtaining multiple quotes is essential. Compare not only the per-unit price but also consider bulk discounts, shipping costs, and acceptable payment terms.
  • Regulatory Compliance and Safety Data: Ensure the supplier adheres to all relevant safety and environmental regulations, and can provide Material Safety Data Sheets (MSDS/SDS) for the product.

The Advantage of Chinese Manufacturers

When seeking 4'-Bromo-N,N-diphenyl-4-biphenylamine, many companies find that partnering with a reliable OLED intermediate manufacturer in China offers distinct advantages. These manufacturers often possess large-scale production facilities, allowing for cost efficiencies and a steady supply. They are experienced in international trade and logistics, making the export process smoother. By thoroughly vetting potential Chinese suppliers, businesses can secure a dependable source for this critical chemical intermediate.

If you are looking for a trusted supplier of 4'-Bromo-N,N-diphenyl-4-biphenylamine, consider manufacturers with a proven track record in producing high-purity electronic materials. Requesting a quote and a sample is the best way to assess their capabilities and ensure they meet your specific needs for advancing OLED technology.
