For procurement professionals in the chemical and pharmaceutical industries, sourcing intermediates like 1,5-Dibromo-2,4-dinitrobenzene (CAS: 24239-82-5) requires a strategic approach, focusing on reliable manufacturers, consistent quality, and competitive pricing. China has established itself as a dominant force in chemical manufacturing, offering a vast array of high-quality intermediates. This guide aims to assist B2B buyers in navigating the procurement process for this specific compound.

Understanding the Product: 1,5-Dibromo-2,4-dinitrobenzene

1,5-Dibromo-2,4-dinitrobenzene is an aromatic organic compound characterized by its yellow powder appearance. With a purity typically exceeding 97%, it serves as a critical intermediate in the synthesis of pharmaceuticals, agrochemicals, and other fine chemicals. Its chemical formula is C6H2Br2N2O4, and its CAS Registry Number is 24239-82-5. Key specifications that buyers should look for include detailed information on purity, physical form, and packaging options (e.g., 25g, 100g, 500g, bulk).

Why Source from China? The B2B Advantage

Chinese chemical manufacturers offer several compelling advantages for international buyers:

  • Cost-Effectiveness: Economies of scale and efficient production processes often translate into more competitive pricing compared to suppliers in other regions. This is a major factor for purchasing managers looking to buy in bulk.
  • Extensive Manufacturing Capabilities: China hosts a vast number of chemical production facilities capable of synthesizing a wide range of complex organic molecules.
  • Established Export Networks: Many manufacturers have years of experience in international trade, simplifying logistics and export procedures.
  • Focus on Quality: Leading Chinese suppliers are increasingly investing in R&D and quality control to meet global standards, often providing detailed Certificates of Analysis (CoA).

Key Steps for Procurement Managers

When you intend to buy 1,5-Dibromo-2,4-dinitrobenzene from China, follow these steps:

  1. Identify Reputable Manufacturers: Utilize industry directories, online chemical marketplaces, and trade shows to find manufacturers with a proven track record in producing intermediates. Look for companies that specialize in aromatic compounds or nitro derivatives.
  2. Request Quotations (RFQ): Contact multiple suppliers with your specific requirements, including desired quantity, purity level, and delivery timeline. Ask for their best price and lead times.
  3. Evaluate Product Specifications and CoA: Carefully review the product specifications and the Certificate of Analysis for each batch. Pay attention to purity, assay methods, and any specified impurities.
  4. Inquire About Packaging and Shipping: Confirm that the packaging is suitable for safe transport and storage. Clarify shipping methods, costs, and estimated delivery times.
  5. Consider Sample Orders: Before committing to large bulk purchases, it is often wise to order a sample to evaluate the product quality and the supplier's responsiveness.
  6. Negotiate Terms: Discuss payment terms, minimum order quantities (MOQ), and any quality guarantees.

Building a Reliable Supply Chain

Establishing a long-term relationship with a trusted Chinese manufacturer for 1,5-Dibromo-2,4-dinitrobenzene can ensure a stable supply for your ongoing projects. By focusing on clear communication, thorough due diligence, and consistent quality evaluation, procurement professionals can secure this vital chemical intermediate effectively and efficiently, supporting their company's R&D and production goals.
