Manufacturing Quality Control of 4-Nitro-L-phenylalanine monohydrate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time relative to reference standards or threshold limits. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to measure water content via stoichiometric reaction with iodine and sulfur dioxide. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify common organic solvents (e.g., methanol, acetone, DMF) based on calibrated response factors. |
| Heavy Metals | ICP-MS | Multi-element detection and quantification of toxic metals (e.g., Pb, Cd, As, Hg) after acid digestion, using mass spectrometry for high sensitivity and specificity. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified against chloride standard calibration curve. |
| Optical Rotation | [alpha]D Measurement | Measurement of specific optical rotation using sodium D-line light source to confirm chiral integrity and enantiomeric purity. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after high-temperature ashing (700–800 C) to determine inorganic ash content. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of pH in a defined aqueous suspension (e.g., 1% w/v) using calibrated glass electrode and pH meter. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using laser scattering to determine volume-based particle size distribution (D10, D50, D90). |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic mesophilic bacteria and fungi by filtration, membrane transfer to appropriate agar media, and colony counting after incubation. |
| Appearance | Visual Inspection | Assessment of physical form, color, and clarity of solid material against established reference standard under controlled lighting conditions. |
