Manufacturing Quality Control of DL-O-METHYLSERINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 200-220 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of impurities (e.g., O-methylserine isomers, serine, methanol-derived by-products) using gradient HPLC-UV. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine-based reagent to determine trace water content based on stoichiometric reaction. |
| Residue on Ignition | Gravimetric Analysis | Heating sample at 750 C to constant weight; residue mass reflects inorganic ash content. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion and plasma emission spectroscopy. |
| Chloride Content | Ion Chromatography | Separation and conductivity detection of chloride ions following aqueous extraction and anion-exchange chromatography. |
| Sulfate Content | Ion Chromatography | Separation and conductivity detection of sulfate ions after sample dissolution and anion-exchange chromatography. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light to confirm stereochemical identity and enantiomeric excess. |
| pH (1% w/v solution) | Potentiometric pH Measurement | Determination of hydrogen ion activity in aqueous solution using calibrated glass electrode and pH meter. |
| Loss on Drying | Thermogravimetric Analysis | Mass loss measured after drying at 105 C for 2 hours, indicating volatile components including residual solvents and moisture. |
| Residual Solvents (e.g., methanol, ethanol) | GC-FID | Headspace gas chromatography with flame ionization detection to quantify low-boiling organic solvents per ICH Q3C guidelines. |
| Microbial Limits | Membrane Filtration and Culture | Enumeration of aerobic mesophilic bacteria and fungi via filtration, membrane transfer to selective media, and colony counting after incubation. |
