For chemists and procurement specialists engaged in pharmaceutical synthesis, understanding the precise specifications of a chemical intermediate is paramount. 5-Methyl-D-norleucine (CAS 138751-02-7) is a specific unnatural amino acid that serves as a valuable building block. This article provides an overview of its key technical aspects and guidance on how to efficiently inquire about its availability and pricing from reputable suppliers.

As a leading manufacturer and supplier in China, NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing clear and comprehensive information about our products. 5-Methyl-D-norleucine, identified by CAS number 138751-02-7, has the molecular formula C7H15NO2 and a molecular weight of approximately 145.1995. Its chemical structure features a chiral center, making it an important component in enantioselective synthesis. While specific physical appearance details are often dependent on the manufacturing batch and purity, such unnatural amino acids are typically supplied as white to off-white powders.

The utility of 5-Methyl-D-norleucine lies in its unique structural configuration, which can impart specific properties when incorporated into larger molecules. It is frequently employed as a pharmaceutical intermediate in the development of novel APIs, where precise stereochemistry is critical. Researchers investigating peptide modifications or seeking to develop novel small molecule therapeutics may find this compound particularly useful.

When looking to buy 5-Methyl-D-norleucine, prospective buyers should prepare to inquire about several key aspects to ensure they are sourcing the right material for their needs. This includes requesting the Certificate of Analysis (CoA) to verify purity (often specified as ≥95% or higher for pharmaceutical applications), enantiomeric excess (ee), and the absence of significant impurities. Understanding the typical lead time for delivery, especially for bulk quantities, is also crucial for project planning.

For procurement managers seeking to secure a reliable supply of 5-Methyl-D-norleucine, engaging directly with a manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. is recommended. When submitting an inquiry, it is beneficial to specify the required quantity, the intended application (to help the supplier understand your needs), and any specific quality requirements. Requesting the latest price information, especially for bulk purchases, will allow for effective budgeting. Our aim is to provide transparent and efficient service to all our clients, ensuring they receive the high-quality pharmaceutical intermediates they require.
