For researchers and procurement managers in the pharmaceutical and biotechnology sectors, sourcing high-purity D-Arginine (CAS 157-06-2) is a critical step in ensuring the success of their projects. This D-isomer of the common amino acid arginine plays unique roles in biological systems and is a sought-after ingredient for advanced research and development. Understanding where to buy D-Arginine and what to look for in a supplier is paramount.

D-Arginine is distinct from its L-isomer in its stereochemical configuration, which often dictates its biological activity and metabolic fate. While L-arginine is a fundamental building block for proteins and a precursor to nitric oxide (NO), D-arginine is generally considered metabolically inactive in many pathways where L-arginine is active. This property makes D-Arginine an invaluable tool in research settings, particularly for studies investigating the L-arginine/nitric oxide pathway. By using D-arginine as a control, scientists can delineate the specific roles of the L-isomer and its downstream products.

The primary applications for high-purity D-Arginine extend into several key areas. In pharmaceutical research, it serves as a crucial intermediate in the synthesis of specific peptide-based drugs, including analogs of vasopressin used in managing bleeding disorders like hemophilia and von Willebrand’s disease. Its unique structure also makes it a subject of study for its potential antiproliferative effects on certain cancer cells, opening avenues for novel therapeutic strategies. For biochemists, D-arginine is indispensable for in vitro experiments, enzyme assays, and probing complex biological mechanisms where stereospecificity is key.

When looking to purchase D-Arginine, several factors come into play, including purity, form, and the reliability of the manufacturer. Typically, D-Arginine is available as a white crystalline powder with assay values often exceeding 98% or 99%. The CAS number 157-06-2 is the universal identifier for this compound, essential for accurate ordering and regulatory compliance. Researchers often seek 'pharmaceutical grade' or 'research grade' D-Arginine to ensure it meets the stringent quality requirements for their applications.

Procurement managers frequently inquire about the D-Arginine price, especially when sourcing in bulk. The cost can fluctuate based on purity, quantity, and the supplier’s geographical location. Manufacturers and suppliers based in China are often competitive providers of high-quality D-Arginine, offering attractive pricing for both small and large orders. When comparing options, it is vital to look beyond the price and consider the supplier's reputation, quality control processes, and ability to provide Certificates of Analysis (CoA) and technical support.

For those seeking to buy D-Arginine, engaging with established manufacturers and specialized chemical suppliers is recommended. Many leading chemical companies now offer D-Arginine online, allowing for quick price comparisons and easy ordering. These suppliers often cater to both laboratory research needs and larger-scale industrial requirements, providing flexibility in quantities. When requesting a quote, be sure to specify the required purity, quantity, and any specific packaging or regulatory documentation needed. Choosing a reputable D-Arginine supplier ensures that your research is supported by materials of the highest integrity.
