Manufacturing Quality Control of 926663-00-5
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at specified wavelength based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV; identification and reporting per ICH Q3B thresholds. |
| Residual Solvents | GC-FID | Measures residual organic solvents (e.g., ethanol, DMF, toluene) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water content via coulometric or volumetric titration using iodine-based redox reaction in anhydrous methanol medium. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Ni, As) by inductively coupled plasma mass spectrometry after acid digestion and dilution. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Sulfate Content | Ion Chromatography | Quantifies sulfate ions via ion chromatography with conductivity detection following sample dissolution and dilution. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (500–600 C) and weighing of the cooled crucible. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against established reference standards. |
| Bulk Density | Tap Density Tester | Measures mass per unit volume after standardized tapping procedure per USP <616> for powder flow characterization. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of dry powder using Mie scattering theory analysis of laser light diffraction pattern. |
