For procurement managers and R&D scientists in the pharmaceutical and agrochemical sectors, sourcing high-quality chemical intermediates is paramount. 3,5-Dichloro-2-fluoropyridine (CAS: 823-56-3) stands out as a crucial building block, particularly in the synthesis of pharmaceuticals. Navigating the global market to find a reliable manufacturer and supplier is a key challenge. This guide aims to provide insights into what to look for when you need to buy this essential compound.

When procuring 3,5-Dichloro-2-fluoropyridine, purity is often the most critical factor. Typically supplied as a white crystalline powder, it should meet stringent purity specifications, often exceeding 98.0% as verified by HPLC. This ensures that downstream reactions proceed efficiently with minimal byproducts, a crucial aspect for pharmaceutical applications where consistency and safety are non-negotiable. Understanding the physical properties, such as its melting point (around 41-43°C), also helps in assessing quality and handling requirements.

Consider the origins of your supply. Chinese manufacturers are increasingly becoming key players in the global chemical supply chain, offering competitive prices and large production capacities. Partnering with a reputable Chinese supplier can provide significant cost advantages and ensure a stable supply for your ongoing needs. When evaluating potential suppliers, always request Certificates of Analysis (COA) and inquire about their quality control processes. Look for established companies that can demonstrate a strong track record in producing and exporting fine chemical intermediates.

Key considerations when purchasing 3,5-Dichloro-2-fluoropyridine include:

  • Purity and Specifications: Ensure the product meets your required purity levels (e.g., ≥98.0% by HPLC).
  • Supplier Reliability: Choose a manufacturer with a proven history of quality and timely delivery.
  • Pricing and Volume: Negotiate competitive pricing, especially for bulk purchases.
  • Packaging and Storage: Confirm appropriate packaging (e.g., 25 KGS/Drum) and recommended storage conditions for maintaining product integrity.
  • Technical Support: Some suppliers offer technical assistance, which can be invaluable for optimizing synthesis.

By focusing on these aspects, procurement professionals can confidently source 3,5-Dichloro-2-fluoropyridine, ensuring the success of their pharmaceutical synthesis projects. When you need to purchase this vital intermediate, remember to prioritize quality and supplier dependability to secure your supply chain.
