Manufacturing Quality Control of O-METHYL-L-THREONINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 205 nm, comparing peak area to a certified reference standard. |
| Optical Rotation | [alpha]D | Measurement of specific rotation using a digital polarimeter at 20 degrees C and sodium D-line (589 nm) in aqueous solution. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent to determine trace water based on stoichiometric reaction. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 degrees C, then weighing the non-volatile inorganic residue after cooling in a desiccator. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals by plasma excitation and optical emission detection. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Related Substances | HPLC-UV | Detection and quantification of structurally similar impurities (e.g., L-threonine, O-methyl-D-threonine) using gradient HPLC. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Direct measurement using calibrated pH electrode in a 10 mg/mL aqueous solution at 25 degrees C. |
| Specific Optical Rotation Purity | Comparison of [alpha]D value | Verification of enantiomeric purity by confirming measured [alpha]D falls within +/- 5% of the literature value for pure O-methyl-L-threonine. |
| Loss on Drying | Thermogravimetric Analysis | Weight loss determination after drying at 105 degrees C under vacuum for 2 hours, expressed as percentage. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample with sulfuric acid followed by ashing at 700 degrees C and gravimetric determination of residual sulfate salts. |
| Microbial Contamination | Membrane Filtration | Quantitative enumeration of aerobic mesophilic microorganisms via filtration, membrane transfer to agar, and colony counting after incubation. |
