In the industrial application of chemical compounds, a thorough understanding of their physical and chemical properties is fundamental to ensuring product quality, process efficiency, and the safety of end products. D-Phenylalanine, a vital chiral amino acid, is no exception. NINGBO INNO PHARMCHEM CO.,LTD., as a dedicated manufacturer and supplier, provides comprehensive data on its D-Phenylalanine to meet the exacting standards of industrial clients.

The chemical identity of D-Phenylalanine is established by its molecular formula, C9H11NO2, and its molecular weight of 165.19 g/mol. Its CAS Registry Number is 673-06-3, a universal identifier crucial for regulatory compliance and procurement. The primary specification for D-Phenylalanine, especially when used as a pharmaceutical intermediate or research chemical, is its assay purity, which typically ranges from 98.5% to 101.0%. This high purity ensures that the compound is predominantly the desired D-enantiomer, minimizing interference from impurities that could affect downstream reactions or product performance.

A critical aspect of D-Phenylalanine's quality profile is its enantiomeric purity. The L-isomer content is strictly controlled, usually at not more than 0.5%. This level of control is essential for applications where stereochemistry is paramount, such as in the synthesis of chiral drugs or specialized peptides. Beyond assay and isomeric purity, other physical and chemical parameters are rigorously monitored. For instance, the Loss on Drying (LOD) is kept to a maximum of 0.3%, indicating minimal water content, which is important for stability and accurate weighing. Similarly, the Residue on Ignition (as sulfate) is limited to no more than 0.1%, signifying low inorganic impurity levels. Limits for heavy metals (as lead, ≤ 10ppm) are also critical for applications where metal contamination is a concern.

The appearance of D-Phenylalanine is typically described as a White Powder, a consistent physical characteristic that aids in visual inspection and handling. Its solubility in water, while not extremely high, is sufficient for many solution-based processes. The specific rotation, a key indicator of its chiral integrity, is also precisely measured and falls within a specified range, such as [α]D20 +33.4° to +35.0° (c=2, water). These detailed specifications, readily available from manufacturers like us, enable formulators and process chemists to predict and control their reactions accurately.
