For procurement professionals and R&D scientists in the pharmaceutical and fine chemical sectors, the selection of chemical intermediates is a critical decision that directly impacts product quality, yield, and regulatory compliance. L-Valinol (CAS 2026-48-4) is one such intermediate, highly sought after for its role in synthesizing potent pharmaceutical compounds. This guide aims to equip buyers with the knowledge to effectively source high-purity L-Valinol, emphasizing key considerations such as purity, specifications, and supplier reliability. If you are looking to buy L-Valinol, understanding these factors is paramount.

The chemical identity of L-Valinol is well-defined by its CAS number: 2026-48-4. This universal identifier ensures that you are procuring the correct compound. Beyond the CAS number, the molecular formula (C5H13NO) and molecular weight (103.16 g/mol) provide further confirmation. However, for pharmaceutical applications, the most critical specifications are its appearance and assay. L-Valinol is typically supplied as a white crystalline powder, indicating a solid physical state. The assay, or purity level, is of paramount importance; pharmaceutical-grade L-Valinol should consistently achieve ≥99.0% purity, often verified by techniques like Gas Chromatography (GC) or Chiral High-Performance Liquid Chromatography (HPLC). Low water content (≤1.0%) is another crucial parameter, as moisture can affect reaction kinetics and product stability.

The primary application driving the demand for L-Valinol is its function as an intermediate in the synthesis of Entegevir, an antiviral drug. The chiral nature of L-Valinol is indispensable here, enabling the stereoselective synthesis of the final API. This means that L-Valinol acts as a chiral scaffold, guiding the formation of the correct enantiomer, which is vital for the drug's therapeutic efficacy and safety profile. Any compromise in the chiral integrity or purity of L-Valinol during sourcing can lead to costly production issues and potentially compromise the final drug product.

When evaluating potential L-Valinol suppliers, several factors should come under scrutiny. Firstly, verify their manufacturing capabilities and adherence to quality management systems. A reputable L-Valinol manufacturer will provide comprehensive documentation, including Certificates of Analysis (CoA) for each batch, detailing the purity, physical properties, and analytical methods used. Secondly, consider their supply chain reliability. Can they consistently deliver the required quantities on time? Do they offer flexible packaging options to meet specific project needs? Many businesses find that sourcing from experienced L-Valinol suppliers in China offers a compelling combination of quality, cost-effectiveness, and robust supply chain management.
