Manufacturing Quality Control of 202189-76-2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 210-230 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; identification based on retention time relative to reference standards. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, ethyl acetate, toluene) per ICH Q3C. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric reaction. |
| Heavy Metals | ICP-MS | Quantitative determination of elemental impurities (e.g., Pb, Cd, As, Hg) after acid digestion and analysis by inductively coupled plasma mass spectrometry. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfate Content | Ion Chromatography | Separation and quantification of sulfate ions using anion-exchange column and suppressed conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after high-temperature ashing at 700-800 C and weighing. |
| Optical Rotation | Polarimetry | Determination of specific optical rotation using sodium D-line light to assess chiral purity and identity. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition temperature range using calibrated capillary method. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample to determine volume-weighted particle size distribution. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Measurement of hydrogen ion activity in a standardized suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
