For professionals involved in the procurement of pharmaceutical raw materials, understanding the specific requirements of compounds like 1,2-Distearoyl-sn-glycero-3-phosphoethanolamine (DSPE) is crucial. DSPE is a high-demand phospholipid, pivotal for the development of advanced drug delivery systems such as lipid nanoparticles (LNPs) and liposomes. This guide provides essential considerations for pharmaceutical buyers looking to buy DSPE effectively.

Understanding DSPE Specifications: More Than Just a Name

When sourcing DSPE, several technical specifications are critical:

  • Chemical Name and CAS Number: The full chemical name is 1,2-Distearoyl-sn-glycero-3-phosphoethanolamine. It is essential to cross-reference the correct CAS number, which for this specific stereoisomer is 61177-32-0. Variations in stereochemistry or purity can significantly impact performance. Always verify the CAS number against your formulation requirements.
  • Purity: For pharmaceutical applications, a high purity level, typically ≥98.0% as determined by methods like HPLC, is non-negotiable. This ensures predictable behavior in complex formulations and compliance with regulatory standards.
  • Appearance: DSPE is usually supplied as a white powder. Deviations in color or form could indicate impurities or degradation.
  • Storage Conditions: DSPE is sensitive to moisture and heat. Proper storage, typically at -20°C, is vital to maintain its integrity and prevent degradation. Ensure your DSPE supplier adheres to these conditions during transport and storage.

Selecting a Reliable DSPE Supplier

The choice of supplier directly influences the quality and availability of your DSPE. Consider these factors when looking for a DSPE supplier in China or elsewhere:

  • Manufacturing Expertise: A manufacturer with a proven track record in phospholipid synthesis and stringent quality control processes is preferable.
  • Documentation and Support: Reliable suppliers will readily provide Certificates of Analysis (CoA), Safety Data Sheets (SDS), and other necessary documentation. They should also offer responsive customer and technical support.
  • Competitive Pricing and Bulk Availability: While quality is paramount, competitive DSPE price is a significant consideration, especially for large-scale production. Inquire about bulk pricing and lead times to ensure your supply chain is robust.
