For businesses and research institutions worldwide, the demand for high-quality N6-Cbz-L-Lysine (CAS 1155-64-2) continues to grow, fueled by its essential role in peptide synthesis and pharmaceutical development. China has emerged as a primary sourcing location for this vital amino acid derivative, offering competitive pricing and substantial manufacturing capacity. This guide aims to assist global buyers in identifying and engaging with reliable N6-Cbz-L-Lysine suppliers in China.

Why Source N6-Cbz-L-Lysine from China?

Several factors make China an attractive hub for sourcing N6-Cbz-L-Lysine:

  • Cost-Effectiveness: Chinese manufacturers often provide highly competitive pricing for bulk quantities, due to economies of scale and efficient production processes.
  • Manufacturing Prowess: The country boasts a large number of chemical manufacturers equipped with advanced synthesis technologies capable of producing N6-Cbz-L-Lysine to exacting standards (typically ≥98.0% purity).
  • Extensive Product Range: Many suppliers offer a wide array of related amino acid derivatives and fine chemicals, allowing for consolidated sourcing.
  • Established Export Networks: The infrastructure for exporting chemicals globally is well-developed, ensuring smoother logistics and customs procedures.

Navigating the Chinese Supplier Landscape

Identifying the right supplier requires a strategic approach:

  • Online B2B Platforms: Websites like Alibaba, Made-in-China, and industry-specific chemical directories are excellent starting points. These platforms list numerous N6-Cbz-L-Lysine manufacturers and suppliers, often providing company profiles, product specifications, and contact information.
  • Trade Shows and Exhibitions: Participating in or following major chemical industry trade shows (e.g., CPhI China) can provide direct interaction with manufacturers and insights into new suppliers.
  • Referrals and Networks: Leveraging industry connections and seeking recommendations from peers who have successfully sourced similar chemicals from China can be highly effective.

Due Diligence for Reliable Sourcing

When evaluating potential N6-Cbz-L-Lysine suppliers in China, thorough due diligence is critical:

  • Verify Credentials: Check for company registration, relevant certifications (e.g., ISO), and a stable operational history.
  • Request Product Samples: Always obtain product samples for independent quality testing before committing to large orders.
  • Scrutinize Certificates of Analysis (CoA): Ensure CoAs are detailed, include purity assays (e.g., by HPLC), and match batch-specific results.
  • Assess Communication and Responsiveness: A supplier's ability to communicate effectively, respond promptly to inquiries, and provide clear information is a good indicator of their professionalism.
  • Understand Lead Times and Logistics: Clarify production lead times for your required quantity and the shipping options available. Discuss Incoterms and payment terms upfront.
  • Consider Pricing: While competitive pricing is attractive, do not let it be the sole deciding factor. Balance cost with quality, reliability, and service. Inquire about price structures for different quantities.

Key Considerations for Your Inquiry

When contacting a supplier, be prepared to provide:

  • The exact product name: N6-Cbz-L-Lysine
  • CAS Number: 1155-64-2
  • Required purity: e.g., ≥98.0%
  • Quantity needed (e.g., kg, tons)
  • Desired packaging
  • Intended use of the product
  • Target price range (if applicable)

By following these guidelines, global buyers can confidently navigate the Chinese market and establish reliable supply chains for N6-Cbz-L-Lysine. Partnering with a reputable manufacturer offers not just cost savings but also access to high-quality materials essential for success in the pharmaceutical and chemical industries.
