For procurement specialists and R&D scientists in the chemical and electronics industries, sourcing high-quality intermediates is critical for project success. 4-Bromo-4'-iodobiphenyl (CAS: 105946-82-5) is one such compound, indispensable for the synthesis of advanced organic electronic materials, particularly for OLED applications. As a buyer, navigating the market to find the right supplier and secure the best price requires a strategic approach. This guide outlines key factors to consider when looking to buy this essential chemical intermediate.

Understanding the Product: Purity and Specifications

The primary application of 4-Bromo-4'-iodobiphenyl is as an intermediate in the synthesis of OLED materials. In this demanding field, even minor impurities can significantly degrade the performance and lifespan of the final product. Therefore, purity is paramount. Most reputable manufacturers will specify an assay of ≥98.0%, and often higher purities are available for specialized applications. Buyers should always request a detailed Certificate of Analysis (CoA) for each batch, verifying not only the primary assay but also the presence and levels of any residual solvents, heavy metals, or related organic impurities. When comparing price, consider the purity offered. A slightly lower price for a lower-purity product might prove more expensive in the long run due to poor performance or the need for further purification steps.

Identifying Reliable Suppliers and Manufacturers

The global market for specialty chemicals includes a vast number of suppliers. For intermediates like 4-Bromo-4'-iodobiphenyl, working with established manufacturers, especially those based in regions with robust chemical production infrastructure like China, can offer significant advantages. Look for suppliers who:

  • Have a proven track record in producing and supplying similar high-purity organic intermediates.
  • Demonstrate strong quality control processes and provide comprehensive documentation (CoA, SDS).
  • Offer transparent pricing and clear communication regarding lead times and shipping.
  • Are responsive to inquiries and provide technical support.

When seeking to purchase 4-Bromo-4'-iodobiphenyl, inquire about their production capacity. If you require bulk quantities, ensuring the manufacturer can meet your demands consistently is vital.

Navigating Pricing and Quotations

The price of 4-Bromo-4'-iodobiphenyl can fluctuate based on raw material costs, production volume, and market demand. When requesting quotations, be specific about your requirements:

  • Exact CAS Number: 105946-82-5
  • Required Purity: e.g., ≥98.0%
  • Quantity: Specify grams, kilograms, or metric tons.
  • Packaging: Standard drums or custom packaging.
  • Delivery terms: Incoterms (e.g., EXW, FOB, CIF) and desired delivery date.

Comparing quotes from multiple qualified suppliers is standard practice. Remember that the lowest price isn't always the best value; consider the overall offering, including quality assurance, reliability, and customer service. Building a long-term relationship with a trusted supplier can lead to better terms and consistent product availability.

Logistics and Packaging Considerations

4-Bromo-4'-iodobiphenyl is typically supplied as a solid powder. Packaging often involves sturdy drums, such as 25 kg drums, designed to protect the product from moisture and contamination during transit and storage. Buyers should confirm the packaging specifications and storage recommendations (e.g., store in a cool, ventilated place, keep in dark place, sealed in dry) with their manufacturer to ensure the product's integrity upon arrival. For international shipments, understanding customs regulations and shipping methods (air freight, sea freight) is also important.

In conclusion, successfully procuring 4-Bromo-4'-iodobiphenyl involves a diligent evaluation of purity, supplier reliability, and competitive yet realistic pricing. By focusing on these key aspects, R&D professionals and procurement managers can ensure they obtain a high-quality intermediate that fuels innovation in OLED technology and beyond. When you are ready to buy, consider partnering with established Chinese manufacturers for a reliable and cost-effective solution.
