The pharmaceutical industry continuously seeks high-purity intermediates to ensure the efficacy and safety of its products. For manufacturers producing Bortezomib (CAS: 179324-69-7), a vital proteasome inhibitor for cancer treatment, N-(tert-Butoxycarbonyl)-L-phenylalanine, or Boc-L-Phenylalanine (CAS 13734-34-4), is a non-negotiable starting material. Procuring this compound reliably and at the required quality standards is a primary concern for R&D scientists and procurement managers.

The Significance of Boc-L-Phenylalanine in Bortezomib Synthesis

Bortezomib is a complex dipeptide boronic acid derivative. Its multi-step synthesis requires precisely protected amino acids to build its characteristic structure. Boc-L-Phenylalanine serves as one of the key chiral building blocks, providing the phenylalanine moiety with a protected amine. The Boc group is essential for controlling reactivity during the synthesis, particularly during peptide bond formation and subsequent modifications leading to the final active pharmaceutical ingredient (API). The purity and stereochemical integrity of the Boc-L-Phenylalanine used directly influence the quality and efficacy of the resulting Bortezomib.

Key Quality Parameters for Bortezomib Production

When sourcing Boc-L-Phenylalanine for Bortezomib manufacturing, B2B professionals should prioritize:

  • High Chemical Purity: Typically greater than 99.0% as determined by HPLC, to minimize impurities in the final drug product.
  • Enantiomeric Purity: Maintaining the L-configuration is critical, as the biological activity of Bortezomib is stereospecific. Suppliers should provide data on optical purity.
  • Consistent Specifications: Lot-to-lot consistency in appearance (white powder), melting point, and impurity profiles is vital for reproducible manufacturing processes.
  • Traceability and Documentation: Availability of comprehensive Certificates of Analysis (CoA), Material Safety Data Sheets (MSDS), and potentially ICH-compliant documentation enhances confidence.

Strategic Sourcing: Finding Your Manufacturer or Supplier

For companies looking to buy Boc-L-Phenylalanine, identifying a reliable supplier is paramount. Many leading chemical manufacturers are based in regions like China, offering competitive price points due to economies of scale and established production infrastructure. When evaluating potential partners, consider their:

  • Manufacturing Capacity: Can they scale up production to meet your commercial demands?
  • Quality Management Systems: Are they ISO certified or follow GMP guidelines?
  • Technical Expertise: Do they offer support and are they responsive to inquiries?
  • Supply Chain Reliability: Can they guarantee timely delivery and stable availability?

Engaging directly with a reputable manufacturer can often lead to better cost efficiencies and direct technical dialogue, helping to ensure that the Boc-L-Phenylalanine (CAS 13734-34-4) you receive meets the stringent requirements for Bortezomib production. It is also beneficial to explore long-term supply agreements to secure consistent material availability at predictable costs.

In conclusion, Boc-L-Phenylalanine is a critical intermediate for Bortezomib synthesis. By diligently selecting a quality-focused supplier who can provide high-purity material consistently, pharmaceutical companies can ensure the successful and efficient production of this important anti-cancer medication.
