Manufacturing Quality Control of L-ARGININE P-NITROANILIDE DIHYDROCHLORIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (H-Arg-PNA.2HCl content) | Acid-base titration | Quantifies active compound by neutralization with standardized NaOH after acid hydrolysis and back-titration. |
| Water content | Karl Fischer titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and a base in methanol. |
| Residual solvents (e.g., methanol, ethyl acetate) | Gas chromatography (GC) | Separates and quantifies volatile organic solvents using a capillary column and flame ionization detection. |
| Heavy metals (Pb, Cd, Hg, As) | ICP-MS | Detects trace metal impurities by ionizing the sample in plasma and measuring mass-to-charge ratios of elemental ions. |
| Chloride content | Potentiometric titration with AgNO3 | Determines chloride ions by precipitation titration using silver nitrate and a silver indicator electrode. |
| Optical rotation | [alpha]D measurement | Measures specific rotation of plane-polarized light to confirm chiral purity and identity. |
| Related substances (impurities) | Reverse-phase HPLC | Separates and quantifies structurally related impurities using C18 column and UV detection at 210 nm. |
| pH (1% aqueous solution) | pH meter measurement | Determines acidity/basicity of aqueous solution using calibrated glass electrode system. |
| Loss on drying (LOD) | Gravimetric analysis | Measures weight loss after controlled heating under vacuum or nitrogen to determine volatile matter. |
| Microbial contamination | Membrane filtration and colony counting | Quantifies aerobic microorganisms by filtration, membrane transfer to agar, and incubation followed by CFU enumeration. |
| Particle size distribution | Laser diffraction | Analyzes particle size by measuring angular variation in intensity of laser light scattered by dispersed particles. |
| Residue on ignition | Gravimetric analysis | Determines inorganic ash content by high-temperature incineration and weighing of residual residue. |
