Manufacturing Quality Control of 4-Nitro-3-phenyl-L-alanine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and peak area normalization. |
| Optical Purity (Enantiomeric Excess) | Chiral HPLC | Enantioseparation on a chiral stationary phase with UV detection; ee calculated from peak areas of L- and D-enantiomer. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection for quantification of common solvents (e.g., methanol, acetone, DMF) per ICH Q3C guidelines. |
| Heavy Metals | ICP-MS | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion and dilution. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine total water content in the sample. |
| Loss on Drying | Gravimetric Analysis | Weight loss measured after drying under controlled temperature and vacuum, indicating volatile and moisture content. |
| pH of Aqueous Solution | Potentiometric pH Measurement | pH determined using calibrated glass electrode in a saturated aqueous suspension or defined solution. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range at which solid-to-liquid phase change occurs. |
| Specific Optical Rotation | [alpha]D Measurement | Rotation of plane-polarized light measured at 589 nm using sodium D-line; reported as specific rotation per g/mL and dm path length. |
| Residue on Ignition | Gravimetric Ash Test | Mass of inorganic residue remaining after high-temperature incineration at 700-800 C. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine volume-based particle size distribution in dispersed sample. |
