Manufacturing Quality Control of CARBAMOYL-DL-ASPARTIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison with reference standard using reversed-phase chromatography and UV detection at 210 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities by reversed-phase HPLC with UV detection, relative to main peak area. |
| Loss on Drying | Gravimetric (105 C oven drying) | Mass loss measured after drying sample at 105 C to constant weight, indicating volatile content including water and solvents. |
| Residue on Ignition | Gravimetric (sulfated ash) | Residue mass after high-temperature incineration in presence of sulfuric acid, indicating inorganic impurities. |
| Heavy Metals | AAS (Flame or Graphite Furnace) | Quantification of Pb, Cd, Hg, As, and other heavy metals by atomic absorption spectroscopy after acid digestion. |
| Chloride | Argentometric Titration (Mohr method) | Titration with standardized silver nitrate solution; endpoint detected by formation of red-brown Ag2CrO4 precipitate. |
| Sulfate | Barium Sulfate Gravimetry | Precipitation as BaSO4 followed by filtration, drying, and weighing to determine sulfate content. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral centers in solution at specified concentration and wavelength. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of hydrogen ion activity in a 1% w/v aqueous solution using calibrated pH electrode. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with KF reagent to quantify water via iodine-sulfur dioxide reaction. |
| Microbial Limits | Membrane Filtration and Plate Count | Enumeration of aerobic mesophilic bacteria and yeasts/molds after filtration, membrane transfer, and incubation on appropriate agar media. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity pattern to calculate particle size distribution in dry or dispersed state. |
