Procuring the right chemical intermediates is a critical function for any research and development or manufacturing operation, especially within the pharmaceutical and fine chemical industries. This guide focuses on the procurement of 2,6-Dichloro-4-(trifluoromethyl)pyridine, identified by CAS number 39890-98-7. Understanding its specifications, market landscape, and best practices for purchase will ensure you secure a reliable supply.

Understanding Product Specifications

When you intend to buy 2,6-Dichloro-4-(trifluoromethyl)pyridine, it's vital to be aware of its key characteristics. The compound, with molecular formula C6H2Cl2F3N and molecular weight 215.99, typically appears as a colorless to light yellow liquid. Critical specifications often include:

  • Purity: Most applications require a minimum purity of 97%, often verified by Gas Chromatography (GC). Higher purity grades may be available for specialized uses.
  • Physical Properties: Boiling point information (e.g., 85°C at 40mm) and density (e.g., 1.505 g/mL at 25°C) are important for handling and process design.
  • Safety Data: Familiarize yourself with hazard symbols (e.g., Toxic, Flammable) and risk statements (e.g., R36/37/38, R25) as well as safety statements (e.g., S26, S36/37/39) from the Material Safety Data Sheet (MSDS). UN classification (e.g., UN 2810) is also crucial for transportation.

Identifying Reliable Suppliers and Manufacturers

The market for 2,6-Dichloro-4-(trifluoromethyl)pyridine includes various suppliers and manufacturers, with a significant portion based in China. As a procurement professional, your focus should be on suppliers who can consistently meet your quality and volume requirements. Key aspects to vet include:

  • Manufacturer vs. Distributor: Direct manufacturers often offer better pricing and greater control over quality and lead times. Distributors may offer wider product ranges but can have higher markups.
  • Supply Capacity: Confirm the supplier's ability to meet your projected demand, whether for laboratory research or larger-scale production.
  • Quality Control Processes: Inquire about their quality assurance systems, batch-to-batch consistency, and the availability of Certificates of Analysis (CoA) for each lot.
  • Reputation and References: Seek feedback or testimonials from other clients, particularly within your industry.

Pricing and Negotiation Strategies

When purchasing 2,6-Dichloro-4-(trifluoromethyl)pyridine, obtaining multiple quotes is standard practice. Pricing can vary based on quantity, purity, and the supplier's manufacturing costs. Consider the following:

  • Volume Discounts: Larger orders typically command lower per-unit prices.
  • Payment Terms: Understand the accepted payment methods (T/T, L/C, PayPal) and terms.
  • Incoterms: Clarify shipping terms (FOB, CFR, CIF, EXW) to understand who is responsible for shipping costs and risks.

The Importance of Samples and Testing

Before committing to a large purchase, always request a sample of 2,6-Dichloro-4-(trifluoromethyl)pyridine. This allows your R&D team to verify the purity, identity, and suitability for your specific applications. A reputable supplier will readily provide samples, often with associated documentation.

By approaching the procurement of 2,6-Dichloro-4-(trifluoromethyl)pyridine with a thorough understanding of its specifications and the market, you can ensure a successful and cost-effective acquisition, supporting your ongoing projects and production needs.
