For procurement managers and R&D scientists in the pharmaceutical and fine chemical sectors, sourcing critical intermediates like 2,4-Dichloro-5-fluoropyrimidine (CAS: 2927-71-1) efficiently and effectively is a key responsibility. This compound serves as a vital building block, particularly in the synthesis of important APIs such as Abemaciclib, making its procurement a strategic decision that impacts project timelines and costs.

Key Specifications to Consider When Buying

When purchasing 2,4-Dichloro-5-fluoropyrimidine, several key specifications should be prioritized to ensure it meets the demands of your application:

  • Purity: This is arguably the most critical factor. For pharmaceutical applications, a minimum purity of 98% is often required, with higher purity levels (e.g., 99%) being preferable for critical synthesis steps. Suppliers should provide a detailed Certificate of Analysis (CoA) confirming purity via methods like HPLC or GC.
  • Appearance: Typically described as a white to pale brown crystalline powder, any significant deviation might indicate issues with the manufacturing or storage process.
  • CAS Number and Synonyms: Always verify the CAS number (2927-71-1) and commonly accepted synonyms to ensure you are ordering the correct chemical.
  • Packaging: For research quantities, small bottles are common, while larger commercial orders may require specialized packaging like drums or intermediate bulk containers (IBCs). Ensure packaging maintains product integrity and complies with shipping regulations.
  • Safety Data: A Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) should be readily available, detailing hazard information, handling precautions, and emergency procedures.

Selecting a Reliable Supplier

Choosing the right supplier is crucial for consistent quality and uninterrupted supply. Consider the following when evaluating potential partners:

  • Manufacturing Capabilities: Look for suppliers with robust manufacturing processes and strong quality management systems (e.g., ISO certification). Manufacturers based in China are often a good source due to their extensive chemical production infrastructure.
  • Technical Support: A supplier that offers technical support, including detailed product specifications and assistance with documentation, adds significant value.
  • Price and Commercial Terms: Obtain quotes from multiple suppliers to compare pricing, especially for bulk quantities. Understand their payment terms, lead times, and minimum order quantities (MOQ).
  • Reputation and Reliability: Research the supplier's track record, read reviews if available, and assess their commitment to customer service.

The Procurement Process: From Inquiry to Delivery

The typical procurement process involves:

  1. Inquiry: Contact potential suppliers with your specific requirements (quantity, purity, delivery timeline).
  2. Quotation: Review quotes, comparing not just price but also specifications, lead times, and terms.
  3. Sample Testing: For critical applications, it is often wise to request a sample for in-house quality verification before placing a large order.
  4. Purchase Order: Issue a formal purchase order specifying all details.
  5. Logistics: Coordinate shipping and ensure all necessary customs documentation is in order.

By following these guidelines, procurement professionals can confidently buy 2,4-Dichloro-5-fluoropyrimidine, securing a vital intermediate that underpins critical pharmaceutical synthesis and R&D efforts.
