Manufacturing Quality Control of AC-MET-OME
| 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 Q3B. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify residual methanol, ethyl acetate, and other process solvents against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content based on stoichiometric reaction with water. |
| Optical Rotation | [alpha]D Measurement | Measurement of specific optical rotation using a polarimeter at 20 C and sodium D-line (589 nm) to confirm chiral integrity and enantiomeric purity. |
| Heavy Metals | ICP-MS | Quantitative determination of Pb, Cd, Hg, As, and other regulated metals after acid digestion, using inductively coupled plasma mass spectrometry for sub-ppb sensitivity. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Sulfate Impurity | Ion Chromatography | Determination of sulfate anions via ion chromatography with conductivity detection following sample dissolution and dilution. |
| Residue on Ignition | Gravimetric Analysis | Weight measurement of inorganic residue remaining after controlled high-temperature ashing (700-800 C) of the sample. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Direct pH measurement of a 1% w/v aqueous solution using calibrated pH electrode and buffer standards. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid-to-liquid phase transition occurs, using standardized capillary method per USP <741>. |
| Microbial Contamination | Membrane Filtration and Plate Count | Enumeration of aerobic mesophilic microorganisms after filtration, membrane transfer to soybean-casein digest agar, and incubation at 30-35 C for 3-5 days. |
