For procurement managers in the chemical and pharmaceutical industries, sourcing high-purity DL-Lysine (CAS 70-54-2) is a critical step in ensuring the success of their synthesis and research projects. As a versatile amino acid derivative, DL-Lysine acts as a fundamental building block for numerous complex compounds, making its quality and consistent availability paramount. This guide aims to equip procurement professionals with the knowledge to select the most suitable DL-Lysine supplier, particularly from leading manufacturing hubs like China.

When evaluating potential DL-Lysine manufacturers, several key criteria should be considered. Firstly, product purity is non-negotiable. Look for suppliers that guarantee a minimum purity level, typically 98% or 99%, and provide Certificates of Analysis (CoA) for each batch. This documentation confirms that the product meets specified standards for appearance (powder), molecular formula (C6H14N2O2), and molecular weight (146.19). A reliable manufacturer will also be transparent about their production processes and quality control measures.

Secondly, supply chain reliability is crucial. As a chemical intermediate, DL-Lysine is often required in significant quantities for ongoing production. Partnering with a supplier that has robust production capacity and efficient logistics ensures that your supply chain remains uninterrupted. Inquire about their production capabilities, lead times, and delivery schedules. A strong supplier will have established relationships with shipping providers, ensuring timely delivery via air, land, or sea freight from ports like Shanghai or Qingdao.

Furthermore, understanding the supplier's pricing structure and willingness to offer competitive rates is essential. Purchasing DL-Lysine in bulk can significantly reduce costs. Engage in direct conversations with manufacturers to obtain the latest price information and explore potential discounts for larger orders. Comparing quotes from multiple reputable suppliers will help secure the best value for your investment.

The application of DL-Lysine spans various fields, including pharmaceutical intermediate synthesis, biochemical research, and as a precursor for specialty chemicals. Understanding your specific application needs will help in communicating your requirements to potential suppliers. For instance, if your project requires DL-Lysine for advanced pharmaceutical synthesis, emphasizing the need for stringent impurity profiles and regulatory compliance is vital.

Finally, customer service and technical support can be a deciding factor. A responsive supplier who can provide technical data, answer queries promptly, and assist with sample requests demonstrates a commitment to partnership. When you're ready to buy DL-Lysine, ensure your chosen manufacturer can support your ongoing needs, making them a strategic ally in your business operations.
