Manufacturing Quality Control of 1-Methyl-5-oxo-3-pyrrolidinecarboxylic acid methyl ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 210 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; identification based on retention time matching and threshold limits per ICH Q3A/B. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, ethyl acetate) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent where water reacts stoichiometrically to determine trace moisture content. |
| Optical Rotation | [alpha]D Measurement | Polarimetric measurement of specific rotation at 20 C using sodium D-line (589 nm) to confirm chiral integrity and enantiomeric purity. |
| Heavy Metals | ICP-MS | Inductively coupled plasma mass spectrometry for simultaneous quantification of elemental impurities (e.g., Pb, Cd, Hg, As) at sub-pptr levels. |
| Chloride Content | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified against chloride standard calibration curve. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-800 C followed by weighing of non-volatile residue after sulfuric acid treatment to assess inorganic impurity load. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change; used for identity confirmation and purity screening. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Electrochemical measurement using calibrated pH electrode in a saturated aqueous suspension to assess acidic/basic degradation products. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against established reference under controlled lighting and against white/black backgrounds. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser scattering to determine D10, D50, D90 values relevant for handling and formulation performance. |
