For procurement managers in the pharmaceutical and fine chemical sectors, identifying reliable suppliers for critical intermediates is a cornerstone of successful operations. 2,6-Dichloro-5-fluoro-3-pyridinecarbonitrile (CAS: 82671-02-1) is one such compound, essential for synthesizing life-saving antibiotics like Gemifloxacin. This guide aims to equip buyers with the knowledge needed to procure this high-purity intermediate effectively, focusing on quality, specifications, and strategic sourcing.

Understanding the Essential Specifications

When sourcing 2,6-Dichloro-5-fluoro-3-pyridinecarbonitrile, rigorous adherence to specifications is non-negotiable. Key parameters to scrutinize include:

  • Purity: The industry standard for this intermediate is generally ≥98%. Higher purity levels ensure better reaction yields and fewer by-products in subsequent synthesis steps, critical for API production.
  • Appearance: It should consistently be an off-white to light tan crystalline powder. Any deviation might indicate contamination or improper storage.
  • Loss on Drying: A low loss on drying (≤1.0%) signifies minimal moisture content, which is important for chemical stability and accurate weighing during formulations.
  • Iron Ion Content: Low levels, such as ≤20 PPM, are often specified to prevent catalytic interference in sensitive chemical reactions.
  • CAS Number: Verification of CAS No. 82671-02-1 ensures you are sourcing the correct chemical entity.

These specifications are vital for ensuring that the intermediate will perform as expected in your manufacturing processes, whether for Gemifloxacin or other advanced fluoroquinolone derivatives. Always request a Certificate of Analysis (CoA) with your order.

Identifying Reliable Manufacturers and Suppliers

The global market for chemical intermediates is vast, with China being a leading producer. When seeking a supplier for 2,6-Dichloro-5-fluoro-3-pyridinecarbonitrile, consider factors that indicate reliability and quality:

  • Manufacturing Experience: Look for manufacturers with a proven track record in producing pharmaceutical intermediates. Companies with expertise in complex heterocyclic synthesis are often preferred.
  • Quality Control Systems: A supplier with robust internal quality control and adherence to international standards (like ISO certifications) is crucial.
  • Supply Chain Stability: Assess their production capacity and ability to meet your volume requirements consistently. A reliable supply chain is critical to avoid production disruptions.
  • Technical Support: Suppliers who can offer technical data, safety information (MSDS), and responsive customer service are invaluable partners.
  • Transparent Pricing: Obtaining quotes for different quantities (from R&D scale to bulk orders) will help in cost management.

Engaging with manufacturers directly, especially those based in China, can often lead to better pricing and direct communication regarding specific requirements.

Commercial Considerations: Price and Purchase

When you are ready to purchase, understanding the pricing structure is essential. Factors influencing the price of 2,6-Dichloro-5-fluoro-3-pyridinecarbonitrile include order volume, purity specifications, and shipping terms. It is advisable to request detailed quotations from multiple pre-qualified suppliers. For significant bulk orders, negotiating terms and exploring long-term supply agreements can yield further cost benefits. When you buy this intermediate, ensure you clarify shipping methods, lead times, and any import/tariff considerations.

Conclusion

Procuring 2,6-Dichloro-5-fluoro-3-pyridinecarbonitrile requires diligence in understanding its specifications and selecting a dependable supplier. By focusing on purity, quality control, and reliable supply chains, procurement managers can ensure they obtain this vital pharmaceutical intermediate, supporting the development and production of critical medicines. For those seeking a trustworthy manufacturer and supplier in China, engaging with experienced providers who offer comprehensive support and competitive pricing is key to a successful partnership.
