Industrial Applications of DL-METHIONINE SULFOXIDE
| Industry | Application | Process |
|---|---|---|
| Animal Feed Additives | Used as an oxidized derivative of methionine to supplement sulfur-containing amino acids in animal feed, supporting protein synthesis and growth performance | Added directly to premixes at the recommended dosage (typically 0.05–0.2%) or co-granulated with vitamins, trace minerals, and other feed components; stored under light-protected and moisture-proof conditions to maintain stability |
| Pharmaceutical Intermediates | Used in the synthesis of methionine-containing peptide drugs, antioxidants, and hepatoprotective agents (e.g., precursor compounds for reduced glutathione) | High-purity isomers, obtained via chiral resolution or asymmetric oxidation, are employed in solid-phase peptide synthesis (SPPS) or solution-phase condensation reactions |
| Cosmetic Ingredients | Used as a mild antioxidant in anti-aging skincare formulations to help maintain redox balance in the stratum corneum and support skin barrier function | Incorporated into the aqueous phase during emulsification (temperature ≤45 °C); pH maintained between 5.0 and 6.5 for optimal stability; commonly used in combination with vitamin E and coenzyme Q10 |
Manufacturing Quality Control of DL-METHIONINE SULFOXIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (DL-Methionine Sulfoxide Content) | HPLC with UV detection | Separation on a reversed-phase column followed by quantification using UV absorbance at 210 nm against a certified reference standard. |
| Optical Rotation | [a]D measurement using polarimeter | Measurement of the rotation of plane-polarized light by a solution of the compound at specified concentration and temperature. |
| Water Content | Karl Fischer titration | Electrochemical titration based on the reaction of iodine with water in a methanol-based solvent system. |
| Residue on Ignition | Gravimetric analysis after ignition | Heating the sample to 700-800 C to oxidize organic matter, then weighing the inorganic residue. |
| Heavy Metals (as Pb) | ICP-OES | Quantification of trace metal impurities after acid digestion, using inductively coupled plasma optical emission spectroscopy. |
| Chloride Impurity | Potentiometric titration with AgNO3 | Titration with silver nitrate using a silver indicator electrode to detect endpoint via potential change. |
| Sulfate Impurity | Barium chloride turbidimetry | Precipitation of sulfate as BaSO4 in acidic medium and measurement of turbidity at 420 nm. |
| Related Substances | HPLC with gradient elution | Separation and detection of structurally related impurities (e.g., methionine, methionine sulfone, dimers) using UV detection. |
| pH of Aqueous Solution | Potentiometric pH measurement | Determination of hydrogen ion activity in a 1% w/v aqueous solution using calibrated pH electrode. |
| Particle Size Distribution | Laser diffraction | Analysis of scattered laser light intensity as a function of angle to determine volume-based particle size distribution. |
| Microbial Contamination | Membrane filtration and colony counting | Filtration of sample solution, transfer to appropriate agar media, incubation, and enumeration of CFUs. |
| Loss on Drying | Thermogravimetric analysis at 105 C | Weight loss measured after drying a sample at 105 C for 2 hours under atmospheric pressure. |
