In the realm of chemical synthesis and pharmaceutical development, the quality of raw materials is paramount. For R&D scientists, procurement managers, and formulation chemists, securing high-purity organic intermediates is not just a preference, but a necessity that directly impacts project success. This guide will explore why purity matters and how to effectively source critical compounds, using 5,12-bis(2-phenylethynyl)tetracene (CAS: 18826-29-4) as an exemplary case.

The Imperative of Purity in Chemical Intermediates

Organic synthesis often involves multi-step processes where even minor impurities in starting materials or intermediates can lead to significant issues. These can include:

  • Reduced reaction yields
  • Formation of undesired by-products
  • Compromised final product efficacy or safety
  • Difficulties in purification
  • Increased production costs

For pharmaceutical intermediates, the stakes are even higher. The purity of a compound like 5,12-bis(2-phenylethynyl)tetracene directly influences the quality and regulatory compliance of the final Active Pharmaceutical Ingredient (API). Researchers and buyers often look for manufacturers who can guarantee high purity levels, such as the 95%min or even 98% purity often associated with this specific tetracene derivative.

Understanding 5,12-bis(2-phenylethynyl)tetracene (CAS: 18826-29-4)

This complex naphthalene derivative, identified by CAS number 18826-29-4, is a key intermediate in various advanced applications. Its molecular formula is C34H20, with a molecular weight of approximately 428.52 g/mol. It typically appears as a white to off-white powder and is known for its stability under normal conditions. Its primary uses lie in organic synthesis and as a building block in pharmaceutical research. Its potential in materials science, particularly in organic electronics like OLEDs, also makes it a compound of significant interest.

Strategies for Effective Sourcing and Procurement

When you are ready to buy 5,12-bis(2-phenylethynyl)tetracene or similar intermediates, consider the following:

  1. Identify Reputable Manufacturers and Suppliers: Look for suppliers with a proven track record, especially those based in China, which has a strong chemical manufacturing sector. Companies that provide detailed Certificates of Analysis (CoA) and technical specifications are preferred.
  2. Prioritize Purity and Specifications: Always verify the purity level and check if it meets your specific application requirements. Inquire about analytical methods used for quality control.
  3. Request Samples: Before placing a large order, request a sample to test its performance in your specific processes. This is a standard practice for discerning buyers.
  4. Inquire About Pricing and Bulk Discounts: When you are ready to purchase, contact the manufacturer or supplier directly for the latest pricing, especially for bulk quantities. Understanding the price per kilogram for various purity grades is crucial.
  5. Assess Supply Chain Reliability: Ensure the supplier can maintain consistent production and delivery schedules. A stable supply chain is vital for uninterrupted R&D and manufacturing.
