Manufacturing Quality Control of N-BENZOYL-DL-METHIONINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 210-230 nm based on peak area comparison to reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., unreacted precursors, degradation products) by comparing retention times and peak areas against qualified reference standards. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, ethyl acetate) using gas chromatography with flame ionization detection and internal standard calibration. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine-based reagent where water reacts stoichiometrically with iodine and sulfur dioxide. |
| Heavy Metals | ICP-OES | Quantifies trace metal impurities (e.g., Pb, Cd, Ni) after acid digestion by measuring element-specific atomic emission intensities in plasma. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with conductivity detection and external calibration. |
| Sulfate Content | Gravimetric Analysis | Precipitates sulfate as barium sulfate under controlled pH and temperature; mass of dried precipitate correlates to sulfate concentration. |
| pH of Aqueous Solution | Potentiometric Titration | Measures hydrogen ion activity using calibrated glass electrode in a saturated aqueous suspension or dilute solution. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid phase using capillary tube and controlled heating rate. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light induced by chiral molecules in solution; confirms racemic nature (near-zero rotation for DL-form). |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by ignition at 700-800 C followed by weighing of residual non-volatile material. |
| Particle Size Distribution | Laser Diffraction | Analyzes particle size by measuring angular variation in intensity of laser light scattered by dispersed particles in liquid or air. |
