DL-Lysine, identified by its CAS number 70-54-2, is a fundamental amino acid derivative with wide-ranging applications across research and industrial sectors. For professionals in the B2B chemical and pharmaceutical markets, understanding its properties and sourcing effectively is crucial. This article provides a detailed overview of DL-Lysine, its key attributes, its role as a chemical intermediate, and guidance on how to secure a reliable supply from manufacturers.

As a racemic mixture, DL-Lysine is composed of both D- and L-enantiomers of lysine. Its physical form is typically a powder, and it is characterized by its molecular formula C6H14N2O2 and a molecular weight of approximately 146.19. These basic properties make it a versatile compound for chemical synthesis and biochemical studies. Its significance extends to being a crucial component in the synthesis of proteins, alkaloids, and various other chemical compounds.

In terms of applications, DL-Lysine serves as a vital chemical intermediate. It is extensively used in the pharmaceutical industry as a building block for active pharmaceutical ingredients (APIs) and in the development of diagnostic reagents. Researchers in biochemical fields utilize DL-Lysine for its role in understanding protein structures, enzymatic functions, and metabolic pathways. Its use as a precursor in biosynthesis also highlights its importance in advanced chemical processes.

For businesses looking to purchase DL-Lysine, identifying a trustworthy manufacturer or supplier is paramount. Key considerations include product purity (often specified as ≥98% or ≥99%), consistent batch-to-batch quality, and reliable delivery. Manufacturers based in China are recognized for their substantial production capacities and competitive pricing for fine chemicals like DL-Lysine. When contacting a supplier, be prepared to discuss your specific needs, including desired quantity, purity, and delivery timelines.

Engaging with suppliers to obtain the latest price information and samples is a standard practice for procurement. Understanding the supplier's ability to meet your volume requirements and their adherence to quality standards, such as ISO certifications, will help ensure a successful partnership. By thoroughly evaluating potential manufacturers, businesses can secure a consistent and high-quality supply of DL-Lysine, thereby facilitating their ongoing research and production goals.
