Manufacturing Quality Control of DL-Arginine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (DL-Arginine Content) | Acid-Base Titration | Quantifies total basic amino groups by titration with standardized HCl solution using methyl orange indicator. |
| Optical Rotation | [alpha]D Measurement | Measures specific rotation of a solution at 20 C using sodium D-line to confirm chiral purity and identity. |
| Loss on Drying | Gravimetric Method | Determines volatile matter content by weight loss after drying at 105 C for 2 hours under standard conditions. |
| Residue on Ignition | Gravimetric Method | Measures inorganic ash content by ignition of sample at 600-700 C followed by weighing of residual residue. |
| Chloride | Silver Nitrate Titration | Quantifies chloride ions via precipitation titration with standardized AgNO3 solution using potassium chromate indicator. |
| Sulfate | Barium Chloride Turbidimetry | Measures sulfate as insoluble BaSO4 precipitate; turbidity is proportional to sulfate concentration. |
| Heavy Metals (as Pb) | Colorimetric Method with Dithizone | Forms colored complex between heavy metals and dithizone in acidic medium; intensity compared to lead standard. |
| Iron | Atomic Absorption Spectroscopy (AAS) | Quantifies Fe by measuring absorbance of ground-state atoms at characteristic wavelength (248.3 nm). |
| Arsenic | Gutzeit Method | Generates arsine gas from sample under acidic reduction, which reacts with mercuric bromide to form colored stain. |
| pH (1% aqueous solution) | Potentiometric Method | Measures hydrogen ion activity using calibrated pH electrode in a 1% w/v aqueous solution. |
| Related Substances | High Performance Liquid Chromatography (HPLC) | Separates and quantifies impurities and enantiomeric/isomeric variants using reversed-phase C18 column and UV detection. |
| Microbial Limits | Membrane Filtration Method | Determines total aerobic microbial count and absence of specified pathogens by filtration, incubation, and colony enumeration. |
