Manufacturing Quality Control of L-METHIONINE SULFOXIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (L-Methionine Sulfoxide Content) | HPLC with UV detection | Separation on a reversed-phase column followed by quantification using UV absorbance at 210 nm relative to a certified reference standard. |
| Optical Rotation | [a]D measurement using polarimetry | Measurement of the angle of rotation of plane-polarized light passing through a solution, indicating enantiomeric purity and identity. |
| Water Content | Karl Fischer titration | Volumetric or coulometric titration based on the stoichiometric reaction of water with iodine and sulfur dioxide in pyridine/methanol medium. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion by measuring absorbance of ground-state atoms in flame or graphite furnace. |
| Residue on Ignition | Gravimetric analysis | Heating sample to 700-800 C to combust organic matter, then weighing inorganic residue as sulfate ash. |
| Chloride Impurity | Potentiometric titration with AgNO3 | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| Sulfate Impurity | Barium chloride turbidimetry | Precipitation of sulfate as BaSO4 in acidic medium and measurement of turbidity proportional to sulfate concentration. |
| Related Substances (Impurities) | HPLC with UV detection | Separation and quantification of structurally related compounds (e.g., methionine, methionine sulfone, homocysteine sulfoxide) using gradient elution. |
| pH of Aqueous Solution | Potentiometric pH measurement | Determination of hydrogen ion activity in a 1% w/v aqueous solution using calibrated glass electrode system. |
| Loss on Drying | Thermogravimetric analysis (TGA) or oven drying | Weight loss measured after drying at 105 C for 2 hours, reflecting volatile content including residual solvents and moisture. |
| Microbial Contamination | Membrane filtration and plate count | Filtration of solution followed by culture on soybean-casein digest agar and trypticase soy agar for aerobic bacteria and fungi enumeration. |
| Particle Size Distribution | Laser diffraction | Analysis of scattered laser light intensity pattern to calculate volume-based particle size distribution in dry or dispersed state. |
