Industrial Applications of Sodium methyl sulfate
| Industry | Application | Process |
|---|---|---|
| Agrochemical Industry | Synthesis of agrochemical intermediates | Serves as a methylating agent in the synthesis of organophosphorus insecticides (e.g., fenitrothion, fenthion) and herbicide intermediates (e.g., methylthiophenol, aryl methyl sulfides). |
| Pharmaceutical Industry | Synthesis of pharmaceutical intermediates | Used in methylation reactions of certain drug molecules to introduce a methylthio group (-SCH₃) or perform methylation modifications. |
| Dye Industry | Synthesis of dye intermediates | Employed in the synthesis of sulfur-containing dye intermediates; methylthiolation improves hue or dyeing performance. |
| Organic Synthesis | Preparation of thioether compounds | Acts as a nucleophile or methylating agent for the preparation of unsymmetrical thioethers and other organosulfur compounds. |
Manufacturing Quality Control of Sodium methyl sulfate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (NaCH3SO4 content) | Acid-base titration | Hydrolysis of sulfate ester followed by titration of liberated methanol with standardized acid. |
| Water content | Karl Fischer titration | Quantitative reaction of water with iodine and sulfur dioxide in pyridine/methanol medium. |
| pH of aqueous solution | Potentiometric pH measurement | Determination of hydrogen ion activity using calibrated glass electrode in 1% w/v aqueous solution. |
| Chloride impurity | Ion chromatography (IC) | Separation and quantification of Cl- anions based on differential migration in ion-exchange column. |
| Sulfate impurity | Gravimetric analysis | Precipitation as BaSO4 followed by filtration, drying, and weighing of the precipitate. |
| Heavy metals (as Pb) | Atomic absorption spectroscopy (AAS) | Quantification of total heavy metals after acid digestion by measuring absorbance at characteristic wavelength. |
| Iron (Fe) content | ICP-OES | Multi-element detection via plasma-excited atomic emission at element-specific wavelengths. |
| Residue on ignition | Gravimetric analysis | Mass loss measurement after high-temperature ashing to determine inorganic non-volatile impurities. |
| Appearance | Visual inspection | Assessment of physical state, color, and presence of visible particulates or discoloration under controlled lighting. |
| Particle size distribution | Laser diffraction | Analysis of light scattering pattern to calculate size distribution of dry powder sample. |
| Bulk density | Graduated cylinder method | Mass per unit volume measured by tapping a known mass into a calibrated cylinder. |
| Loss on drying | Thermogravimetric analysis (TGA) | Weight loss measurement upon heating to 105 C under nitrogen to determine volatile content. |
