Manufacturing Quality Control of COMU
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at characteristic wavelength. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC separation and UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., ethyl acetate, DMF) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration with iodine-based reagent. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Ni) using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after anion exchange. |
| Residual Catalyst (Pd) | ICP-OES | Measures palladium residue by atomic emission spectroscopy following acid digestion. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines acidity/basicity of a standardized aqueous suspension using calibrated pH electrode. |
| Melting Point | Capillary Melting Point Apparatus | Identifies temperature range of solid-to-liquid phase transition using controlled heating and visual observation. |
| Bulk Density | USP <616> Tap Density Method | Measures mass per unit volume after standardized tapping to assess flow and packing behavior. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular scattering pattern of laser light passing through dispersed particles. |
| Microbial Contamination | Membrane Filtration and Plate Count | Detects aerobic microorganisms by filtration, membrane transfer to agar media, and colony enumeration. |
