Manufacturing Quality Control of L-Proline sodiuM salt
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (L-proline sodium salt content) | Acid-base titration | Quantifies the main component by titrating with standardized HCl solution using an indicator or potentiometric endpoint detection. |
| Water content | Karl Fischer titration | Measures water by electrochemical reaction between iodine, sulfur dioxide, and water in a methanol-based reagent. |
| pH (1% aqueous solution) | pH meter measurement | Determines hydrogen ion activity in a standardized aqueous solution using calibrated glass electrode system. |
| Specific optical rotation | [a]D measurement | Measures the degree of rotation of plane-polarized light by chiral L-proline sodium salt in solution at 20 C and 589 nm. |
| Heavy metals (as Pb) | Colorimetric sulfide precipitation | Compares sample color intensity after reaction with thioacetamide under controlled pH to lead standard solutions. |
| Chloride impurity | Ion chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate impurity | Barium sulfate gravimetry | Precipitates sulfate as BaSO4 and determines content by weighing the dried precipitate. |
| Residue on ignition | Gravimetric analysis | Measures non-volatile inorganic residue after high-temperature incineration at 700-800 C. |
| Related substances (impurity profile) | HPLC with UV detection | Separates and quantifies structurally related impurities using reversed-phase chromatography and UV absorbance at 200-210 nm. |
| Microbial contamination (Total aerobic count) | Membrane filtration and plate count | Filters sample, incubates on nutrient agar, and counts colony-forming units after 48-72 h at 30-35 C. |
| Loss on drying | Thermogravimetric analysis | Measures mass loss after heating at 105 C for 2 h under atmospheric pressure to determine volatile content. |
| Sodium content | Flame photometry | Quantifies sodium ions by measuring characteristic emission intensity at 589 nm in flame atomization. |
