Procuring essential chemical intermediates is a critical task for any R&D department or manufacturing facility. For those involved in pharmaceutical synthesis, especially peptide synthesis, obtaining high-purity N-alpha-FMOC-Nepsilon-BOC-L-Lysine (CAS 71989-26-9) is non-negotiable. This guide aims to assist procurement managers and researchers in making informed decisions when looking to buy this vital amino acid derivative.

Understanding the Product: N-alpha-FMOC-Nepsilon-BOC-L-Lysine

N-alpha-FMOC-Nepsilon-BOC-L-Lysine is a protected form of the amino acid lysine, specifically engineered for use in Fmoc-based solid-phase peptide synthesis (SPPS). The FMOC group on the alpha-amino position and the BOC group on the epsilon-amino position provide orthogonal protection, allowing for controlled and sequential amino acid coupling.

Key Considerations When Purchasing:

  • Purity: Always prioritize products with a stated purity of 97% or higher. Impurities can lead to side reactions, lower yields, and complicate downstream purification. When you buy, check the Certificate of Analysis (CoA) for detailed purity information.
  • CAS Number Verification: Ensure the CAS number is correctly listed as 71989-26-9 for N-alpha-FMOC-Nepsilon-BOC-L-Lysine. This unique identifier guarantees you are procuring the exact chemical entity required.
  • Supplier Reputation: Choose suppliers with a proven track record in manufacturing and supplying pharmaceutical intermediates. Look for testimonials, certifications (like ISO), and a clear commitment to quality. As a dedicated manufacturer, we pride ourselves on reliability.
  • Pricing and Bulk Options: While quality is paramount, competitive pricing is also a factor. Inquire about bulk purchase discounts if your needs are substantial. Understanding the price per unit for different quantities will help optimize your budget.
  • Packaging and Storage: The product is typically supplied as a white powder. Proper packaging and recommended storage temperatures (often below +30°C) are crucial for maintaining its stability and integrity.
