The efficient synthesis of Valsartan, a widely prescribed angiotensin II receptor antagonist, hinges on the strategic procurement of its key intermediates. Among these, N-(2'-Cyanobiphenyl-4-ylmethyl)-L-valine Methyl Ester Hydrochloride (CAS: 482577-59-3) plays a pivotal role. As a seasoned manufacturer and supplier in China, we understand the intricacies involved in optimizing this crucial step in pharmaceutical production. This guide offers insights for R&D scientists and procurement professionals aiming to secure a reliable and high-quality supply.

Understanding the Intermediate's Value Proposition

N-(2'-Cyanobiphenyl-4-ylmethyl)-L-valine Methyl Ester Hydrochloride is more than just a chemical compound; it's a critical building block designed for specific reactivity. Its molecular structure, featuring a biphenyl moiety with a nitrile group and an L-valine methyl ester component, is precisely engineered to facilitate subsequent chemical transformations in the Valsartan synthesis pathway. The 'hydrochloride' designation indicates it is in a salt form, often chosen for enhanced stability and solubility. When considering to buy this intermediate, understanding its chemical properties and how they align with your specific synthetic route is fundamental.

Quality Metrics that Matter for API Production

For pharmaceutical applications, the quality of an intermediate is non-negotiable. We emphasize the importance of specific metrics when procuring N-(2'-Cyanobiphenyl-4-ylmethyl)-L-valine Methyl Ester Hydrochloride:

  • Assay Purity: A high assay, such as our standard of ≥98.5% (HPLC), ensures that the majority of the material is the desired compound, minimizing side reactions and waste.
  • Impurity Profiling: The presence of specific impurities can derail a synthesis or contaminate the final API. We control critical impurities, like 2-Cyano-4'-bromomethylbiphenyl (≤0.5%), to meet stringent regulatory standards.
  • Physical Form: The product is presented as a white crystalline powder, which is generally easier to handle, weigh, and dissolve compared to amorphous solids or liquids.
  • Loss on Drying: A low loss on drying (≤1.0%) indicates minimal moisture content, contributing to the compound's stability and accurate weighing.
