For procurement managers and R&D scientists in the pharmaceutical and biotech sectors, sourcing critical raw materials like Sirolimus (Rapamycin) is paramount. Understanding the nuances of obtaining high-purity compounds such as Sirolimus (Rapamycin) with CAS number 53123-88-9 is essential for successful product development and research outcomes. This guide focuses on the practical aspects of sourcing this vital immunosuppressant and mTOR inhibitor.

Understanding Sirolimus (Rapamycin)
Sirolimus, also known as Rapamycin, is a macrolide compound with significant immunosuppressive and antiproliferative properties. Its primary applications include preventing organ transplant rejection and treating conditions like lymphangioleiomyomatosis. Furthermore, its role as an mTOR inhibitor has opened avenues for research in cancer therapy, aging, and various other biological processes. When procuring Sirolimus (Rapamycin), ensuring high purity, typically 99%, is crucial for reliable and effective results.

Key Considerations for Buyers
When looking to buy Sirolimus (Rapamycin) powder, several factors should be top of mind for procurement professionals:

  • Purity and Quality: Always prioritize suppliers that guarantee high purity (e.g., 99%) and provide Certificates of Analysis (CoA) detailing analytical results such as HPLC and NMR data. This ensures the material meets pharmacopeial standards if required.
  • Supplier Reliability: Identifying a dependable manufacturer or supplier is key. Look for companies with a proven track record, robust quality management systems (like ISO or GMP compliance), and a stable supply chain. Manufacturers in China are often a cost-effective source for pharmaceutical intermediates.
  • Regulatory Compliance: Ensure the supplier can provide necessary documentation and comply with international regulations for chemical sourcing and shipping.
  • Pricing and MOQs: Compare pricing structures and minimum order quantities (MOQs) from different suppliers. While competitive pricing is important, it should not compromise quality or reliability.
  • Technical Support and Lead Times: A responsive supplier offering technical support can be invaluable. Understanding lead times for delivery is also critical for production planning.

Sourcing Sirolimus (Rapamycin) from China
China has emerged as a significant global hub for pharmaceutical raw materials and intermediates. For buyers seeking Sirolimus (Rapamycin) CAS 53123-88-9, working with reputable Chinese manufacturers can offer significant advantages in terms of cost and availability. However, it is essential to conduct thorough due diligence on potential suppliers. Look for established companies that prioritize quality control and international export standards. For example, sourcing from a dedicated Sirolimus (Rapamycin) supplier China often means direct access to manufacturing capabilities and better price points.

The Importance of the CAS Number
The CAS number 53123-88-9 uniquely identifies Sirolimus (Rapamycin). When requesting quotes or placing orders, always use this CAS number to ensure accuracy. This helps avoid confusion with similar compounds and guarantees you are procuring the correct substance for your needs.

Call to Action for Buyers
For procurement managers looking to secure a reliable supply of high-purity Sirolimus (Rapamycin) powder, engaging with experienced manufacturers is the best approach. Consider reaching out to established suppliers who can provide comprehensive product data, competitive pricing, and consistent delivery. Exploring options from a trusted Sirolimus (Rapamycin) manufacturer can streamline your procurement process and support your research and development goals effectively.
