Manufacturing Quality Control of Dimethyl L-aspartate hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies active ingredient by neutralizing the hydrochloride salt with standardized NaOH solution using an indicator or potentiometric endpoint. |
| Water Content | Karl Fischer Titration | Measures water via iodine-sulfur dioxide reaction in a methanol-based solvent, with coulometric or volumetric detection. |
| Residual Solvents | Gas Chromatography (GC) | Separates and quantifies volatile organic solvents (e.g., methanol, dichloromethane) using a capillary column and FID detector. |
| Heavy Metals | ICP-OES | Determines trace metal impurities (e.g., Pb, Cd, Ni) by plasma excitation and elemental emission spectroscopy. |
| Chloride Content | Argentometric Titration | Measures chloride ions by precipitation with standardized silver nitrate solution using potassium chromate or potentiometric endpoint. |
| Specific Optical Rotation | Polarimetry | Determines enantiomeric purity by measuring the angle of rotation of plane-polarized light in solution at specified wavelength and temperature. |
| Related Substances | HPLC-UV | Separates and quantifies structurally related impurities using reversed-phase chromatography and UV detection at 200–220 nm. |
| pH (1% aqueous solution) | pH Meter Measurement | Measures hydrogen ion activity in a standardized aqueous solution using calibrated glass electrode system. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by ignition at 700–800 C followed by precise weighing of residual residue. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution in suspension via angular scattering pattern analysis of laser beam. |
| Microbial Contamination | Membrane Filtration | Detects aerobic microorganisms by filtering sample through membrane, incubating on nutrient agar, and counting colony-forming units. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using controlled heating and visual observation. |
