In the world of chemical manufacturing and pharmaceutical development, the quality of raw materials directly dictates the success and reliability of the final product. N-Methyl-D-Alanine (CAS: 29475-64-7) is no exception, and understanding its key quality specifications is paramount for any scientist or manufacturer employing it in their processes. As a leading manufacturer in China, we prioritize delivering N-Methyl-D-Alanine that adheres to the highest industry standards.

One of the most critical specifications for N-Methyl-D-Alanine is its assay, which typically ranges from 98.5% to 101.0%. This high assay value ensures a significant concentration of the active compound, minimizing the presence of unwanted byproducts or impurities that could interfere with synthesis reactions. For pharmaceutical intermediates, such purity is non-negotiable, directly impacting the efficacy and safety of the end drug product.

Another crucial aspect is the specific rotation, denoted as [α]D20, which for N-Methyl-D-Alanine falls between +14.3° and +15.2°. This optical property is a direct indicator of the compound's chirality – the specific spatial arrangement of its atoms. In chiral synthesis, maintaining this specific stereochemistry is vital for achieving the desired biological activity or material property. Deviations in specific rotation can signify contamination with the enantiomer or other optically active impurities.

Furthermore, specifications like pH (5.5-7.0), transmittance (≥98.0%), and low limits for loss on drying (≤0.20%) and residue on ignition (≤0.10%) all contribute to the overall quality and suitability of N-Methyl-D-Alanine. These parameters provide insights into the compound's stability, handling characteristics, and freedom from inorganic contaminants.

For those looking to buy N-Methyl-D-Alanine, partnering with a reputable supplier in China that provides detailed Certificates of Analysis (CoA) is essential. These documents confirm that the product meets all specified parameters. By adhering to these rigorous N-Methyl-D-Alanine quality specifications, manufacturers can achieve consistent, reliable results in their complex chemical synthesis and pharmaceutical development projects.

Ensuring these quality benchmarks are met is fundamental to our role as a trusted N-Methyl-D-Alanine supplier. It empowers our clients to innovate with confidence, knowing they are working with a material of the highest caliber.
