For purchasing professionals in the chemical industry, the consistent and cost-effective procurement of essential raw materials like DL-Lysine (CAS 70-54-2) is fundamental to operational success. DL-Lysine, a racemic amino acid derivative, serves as a crucial intermediate in a multitude of synthesis processes, from pharmaceuticals to specialty chemicals. This guide provides practical advice for procurement specialists aiming to source high-quality DL-Lysine and establish dependable supplier relationships.

The first step in procuring DL-Lysine involves a thorough understanding of its specifications. Key parameters to verify include its CAS number (70-54-2), molecular formula (C6H14N2O2), molecular weight (146.19), and physical appearance, which is typically a powder. Purity levels, commonly stated as 98% or 99%, are critical for its function as a chemical intermediate, especially in sensitive applications like pharmaceutical synthesis.

When seeking a DL-Lysine manufacturer, prioritizing suppliers with a proven track record in the fine chemical sector is advisable. Companies operating in China are often primary sources for competitively priced DL-Lysine, offering substantial manufacturing capacities. Purchasing professionals should actively seek suppliers who can provide comprehensive product documentation, including Certificates of Analysis (CoA) that detail purity, assay, and impurity profiles. Requesting samples is also a standard procedure to assess product quality firsthand.

Negotiating price is a key aspect of procurement. As a bulk chemical intermediate, DL-Lysine's cost can vary significantly based on quantity and supplier. Engaging with multiple manufacturers allows for effective price comparison and negotiation. Understanding Incoterms (such as FOB, CFR, CIF) and payment terms (L/C, T/T) is also vital for managing the financial aspects of the purchase and ensuring smooth international transactions.

Beyond price and quality, the reliability of the supply chain cannot be overstated. Purchasing professionals must assess a supplier's production capacity, lead times, and shipping capabilities. Proactive communication with the supplier regarding delivery schedules and potential disruptions is essential for maintaining inventory levels and meeting production deadlines. Ultimately, building a strong relationship with a reputable DL-Lysine supplier can lead to more efficient procurement processes and contribute to the overall success of chemical manufacturing operations.
