Manufacturing Quality Control of DL-CITRULLINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with UV detection | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV absorbance at ~210 nm. |
| Specific Optical Rotation | [α]D | Measurement of optical rotation using a polarimeter at 20 °C with sodium D-line (589 nm) to confirm absence of significant enantiomeric excess. |
| Loss on Drying (LOD) | Gravimetric thermogravimetry | Mass loss determined after drying a sample at 105 °C until constant weight, reflecting volatile content including water and residual solvents. |
| Residue on Ignition (Sulfated Ash) | Gravimetric ash analysis | Residue mass after high-temperature incineration (~700–800 °C) following sulfuric acid treatment, indicating inorganic impurities. |
| Heavy Metals (as Pb) | ICP-OES or AAS | Quantification of total heavy metals (e.g., Pb, Cd, Hg, As) by atomic emission or absorption spectroscopy after acid digestion and matrix-matched calibration. |
| Chloride Content | Potentiometric titration with AgNO₃ | Titration with standardized silver nitrate solution using a silver indicator electrode; endpoint detected by potential inflection due to AgCl precipitation. |
| Sulfate Content | Gravimetric precipitation as BaSO₄ | Precipitation of sulfate as barium sulfate under controlled acidic conditions, followed by filtration, drying, and weighing. |
| Related Substances | HPLC with UV detection | Separation and quantification of structurally related impurities (e.g., L-arginine, L-ornithine, urea derivatives) using gradient reversed-phase HPLC and UV detection. |
| Water Content | Karl Fischer titration | Volumetric or coulometric determination of water via iodine–sulfur dioxide reaction in anhydrous methanol/pyridine medium. |
| Microbial Limits | Membrane filtration followed by plate count | Enumeration of aerobic mesophilic bacteria and detection of specified pathogens (e.g., E. coli, Salmonella) using selective agar media and incubation per pharmacopoeial guidelines. |
