Manufacturing Quality Control of DL-Asparagine hydrate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (DL-Asparagine Monohydrate) | Acid-Base Titration with HCl | Quantifies total amino acid content via back-titration after reaction with standardized HCl and excess NaOH. |
| Water Content | Karl Fischer Titration | Measures water by coulometric or volumetric reaction between water and iodine in pyridine/methanol medium. |
| Specific Optical Rotation | Polarimetry | Determines optical activity using plane-polarized light to assess enantiomeric composition and purity. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Evaluates acidity/basicity of a defined aqueous solution using calibrated pH electrode. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies trace heavy metals by measuring absorption of characteristic wavelength light by ground-state atoms in flame. |
| Sulfated Ash | Gravimetric Analysis | Determines inorganic residue after controlled high-temperature combustion and weighing. |
| Chloride | Argentometric Titration (Mohr method) | Measures chloride ions by titration with silver nitrate using potassium chromate indicator. |
| Sulfate | Barium Sulfate Gravimetric Method | Precipitates sulfate as BaSO4, followed by filtration, drying, and weighing. |
| Residue on Ignition | Gravimetric Analysis | Quantifies non-volatile impurities remaining after ignition at specified temperature. |
| Related Substances | High Performance Liquid Chromatography (HPLC) | Separates and quantifies structurally similar impurities using reversed-phase C18 column and UV detection. |
| Microbial Limits | Membrane Filtration and Plate Count | Detects aerobic microorganisms by filtration, culture on agar media, and colony enumeration. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution by analyzing angular variation in intensity of laser light scattered by suspended particles. |
