For scientists and procurement specialists, acquiring high-quality chemical reagents like 1,2-Diphenylethylenediamine (CAS 16635-95-3) is fundamental to the success of any research or manufacturing endeavor. Ensuring the purity and reliability of such compounds requires a diligent approach to sourcing and quality control. This guide outlines essential considerations when you intend to buy this important organic intermediate.

Understanding the Product: 1,2-Diphenylethylenediamine

1,2-Diphenylethylenediamine, identified by its CAS number 16635-95-3, is a diamine compound. It is commonly found as a white powder and is prized for its utility in various chemical synthesis applications, particularly in pharmaceutical development and as a building block for specialty chemicals. Its molecular formula is C14H16N2, and it has a molecular weight of 212.29. The purity of the material, often specified as 99%, is a critical parameter that directly impacts the outcome of subsequent chemical reactions.

Key Factors in Purchasing Decisions

When it comes to purchasing 1,2-Diphenylethylenediamine, several factors are crucial:

  • Purity Verification: Always request a Certificate of Analysis (CoA) from your supplier. The CoA provides lot-specific data on purity, physical properties, and any detected impurities. This is your primary tool for ensuring the material meets your stringent requirements.
  • Supplier Credibility: Choose suppliers with a strong reputation in the chemical industry. Look for companies that provide detailed product information, clear safety data sheets (SDS), and demonstrate a commitment to quality control. Sourcing from a known manufacturer can often provide greater assurance.
  • Competitive Pricing and Quotations: Obtain multiple quotes for 1,2-Diphenylethylenediamine to compare price points. However, ensure that the lowest price does not compromise quality or reliability. Consider the total cost of ownership, including shipping and potential quality issues.
  • Packaging and Handling: Confirm that the product is packaged appropriately to maintain its integrity during transit and storage. Understanding recommended storage conditions, such as temperature and atmosphere, is also vital.

Leveraging Manufacturer Networks

For organizations looking to purchase this intermediate, tapping into established networks of manufacturers and suppliers is highly beneficial. Companies that specialize in fine chemicals and offer direct-from-manufacturer sourcing often provide better value and more consistent product. Whether you are a research laboratory or a large-scale production facility, careful selection of your chemical supplier is a cornerstone of successful operations.

By focusing on these quality assurance measures, researchers and manufacturers can confidently acquire the 1,2-Diphenylethylenediamine necessary for their critical chemical processes.
