Manufacturing Quality Control of 63422-71-9
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at characteristic wavelength, calibrated against certified reference standard. |
| Related Substances | HPLC-UV or UPLC-MS | Separation and detection of structurally related impurities using gradient HPLC/UV or hyphenated UPLC-MS for identification and quantification. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., ethanol, acetone, DMF) based on retention time and peak area calibration. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation and stoichiometric reaction with water in anhydrous methanol-based medium. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using isotopic detection with high sensitivity and low detection limits. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and conductivity detection of chloride ions in aqueous extract; quantified against chloride standard calibration curve. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measurement of non-volatile inorganic residue after controlled high-temperature ashing (500–600 °C) in a platinum crucible. |
| Optical Rotation | [α]D Measurement | Determination of specific rotation using sodium D-line light in solution at specified concentration, temperature, and path length to confirm chiral integrity. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition detection by observing solid-to-liquid phase change under controlled heating rate, indicating purity and identity. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Direct measurement using calibrated glass electrode in saturated aqueous suspension or defined dilution to assess acidic/basic impurities. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample via angular scattering pattern of laser beam to determine volumetric particle size distribution. |
| Microbial Contamination | Membrane Filtration & Colony Count | Enumeration of aerobic microorganisms and absence of specified pathogens (e.g., E. coli, S. aureus) per pharmacopeial compendia (e.g., USP <61>, <62>). |
