For procurement managers and R&D scientists in the pharmaceutical and fine chemical industries, sourcing high-quality intermediates is paramount to successful product development. One such crucial compound is 2,3,4,6-Tetra-O-benzyl-D-glucopyranose (CAS: 4132-28-9), a protected carbohydrate derivative widely used in complex organic synthesis. This guide aims to equip you with the knowledge to effectively buy this essential chemical, focusing on purity, reliable supply, and competitive pricing from reputable manufacturers.

Understanding the Demand for 2,3,4,6-Tetra-O-benzyl-D-glucopyranose

This benzylated glucopyranose derivative is a vital building block, particularly in the synthesis of pharmaceuticals targeting diseases such as Alzheimer's, diabetes, and cancer. Its protected hydroxyl groups allow for selective reactions, making it indispensable in glycosylation reactions and the construction of complex carbohydrate structures. Researchers often seek this compound for its role in developing new drug candidates and understanding intricate biochemical pathways. When you're looking to purchase this intermediate, ensuring a high purity level, typically ≥98% or ≥99%, is critical for achieving reproducible and accurate synthesis results.

Key Considerations When Sourcing

  • Purity and Specifications: Always verify the purity (e.g., ≥99.0% via HPLC) and check that the product meets all specified parameters such as melting point, optical rotation, and absence of impurities. Reputable suppliers will provide detailed Certificates of Analysis (CoA).
  • Supplier Reliability and Origin: Partnering with established manufacturers, especially those based in regions known for chemical production like China, can offer cost advantages and a stable supply chain. Look for suppliers with a proven track record and robust quality control processes.
  • Pricing and Packaging: Obtaining competitive price quotes is essential. Consider the packaging options available (e.g., 25kg drums) and storage recommendations (e.g., -20°C, protected from light) to ensure product integrity upon arrival. Negotiating terms for bulk purchases can significantly reduce unit costs.
  • Technical Support and Documentation: A good supplier will offer comprehensive technical documentation, including Safety Data Sheets (SDS) and technical data, and may provide custom synthesis services if specific modifications are needed.

How to Secure Your Supply

When you need to buy 2,3,4,6-Tetra-O-benzyl-D-glucopyranose, it's advisable to reach out to multiple trusted chemical manufacturers and suppliers to compare offerings. Requesting samples for quality evaluation before placing a large order is a prudent step. Engaging with your potential supplier to discuss your specific application and quantity requirements can also help in securing the best possible price and delivery terms. For your critical research and production needs, choosing a reliable partner is key to success.
