Manufacturing Quality Control of Z-DL-ASPARAGINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies asparaginic acid content by titration with standardized NaOH using phenolphthalein indicator. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric reaction between water and iodine in pyridine/methanol medium. |
| Specific Optical Rotation | Polarimetry | Determines enantiomeric purity by measuring rotation of plane-polarized light at specified wavelength and temperature. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies Pb, Cd, Hg, As by atomization and absorption of element-specific UV-Vis radiation. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities after high-temperature ashing and weighing. |
| Chloride | Silver Nitrate Titration | Detects chloride ions by precipitation titration with AgNO3 using potassium chromate indicator. |
| Sulfate | Barium Sulfate Gravimetry | Quantifies sulfate as insoluble BaSO4 precipitate formed after digestion and filtration. |
| Iron | 1,10-Phenanthroline UV-Vis Spectrophotometry | Measures Fe2+ complex absorbance at ~510 nm after reduction and chelation. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated glass electrode and reference electrode. |
| Related Substances | Reverse-Phase HPLC | Separates and quantifies impurities using C18 column, UV detection, and gradient elution. |
| Microbial Limits | Membrane Filtration and Plate Count | Detects aerobic microorganisms by filtration, membrane transfer to agar media, and colony enumeration. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution based on angular variation of scattered laser light intensity. |
