Manufacturing Quality Control of DL-Asparagine monohydrate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (DL-Asparagine Monohydrate Content) | Acid-Base Titration | Quantifies main component by titration with standardized HCl after dissolution in water and addition of formaldehyde. |
| Loss on Drying | Gravimetric Analysis | Measures weight loss after drying at 105 C for 2 hours to determine moisture and volatile content. |
| Specific Optical Rotation | Polarimetry | Determines optical activity using sodium D-line light to confirm chiral purity and identity. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in a 1% w/v aqueous solution using calibrated pH electrode. |
| Chloride Impurity | Argentometric Titration (Mohr Method) | Quantifies chloride ions via precipitation with silver nitrate in neutral medium using potassium chromate indicator. |
| Sulfate Impurity | Barium Sulfate Gravimetric Method | Precipitates sulfate as BaSO4 in acidic medium; mass of precipitate determines sulfate content. |
| Heavy Metals (as Pb) | Colorimetric Limit Test (Thioacetamide Method) | Forms colored metal sulfide complexes in acidic medium; compares intensity against lead standard solution. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after ignition at 600-700 C for 30 minutes. |
| Iron Impurity | UV-Vis Spectrophotometry | Measures absorbance of Fe-1,10-phenanthroline complex at ~510 nm after reduction and chelation. |
| Related Substances | HPLC with UV Detection | Separates and quantifies impurities (e.g., aspartic acid, ammonium salts) using reversed-phase C18 column and UV detection at 200 nm. |
| Microbial Limits | Membrane Filtration and Plate Count | Detects aerobic microorganisms and absence of specified pathogens by filtration, incubation, and colony enumeration. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by measuring angular variation in intensity of laser light scattered by suspended particles. |
