Industrial Applications of S-Methyl methanethiolsulfonate
| Industry | Application | Process |
|---|---|---|
| Agriculture | Soil disinfection to control soil-borne diseases, nematodes, and weeds | Applied as a soil fumigant; the compound decomposes to generate methyl isothiocyanate after application and plastic film covering |
| Chemical Manufacturing | Organic synthesis intermediate | Used in the synthesis of other organosulfur compounds or as a reagent in experimental research |
Manufacturing Quality Control of S-Methyl methanethiolsulfonate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration based on iodine consumption in stoichiometric reaction with water. |
| Residual Solvents (e.g., methanol, dichloromethane) | Headspace Gas Chromatography (HS-GC) with FID or MS detection | Volatiles are extracted into headspace gas and separated/quantified via GC calibration curves. |
| Acidity (as H₂SO₄) | Acid-Base Titration with NaOH and potentiometric endpoint detection | Neutralization of acidic impurities using standardized sodium hydroxide; endpoint determined by pH inflection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS (Inductively Coupled Plasma Mass Spectrometry) | Element-specific detection after acid digestion and plasma ionization; offers sub-ppt sensitivity. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Compares sample absorbance at 455 nm to APHA platinum-cobalt standard scale. |
| Density at 20 °C | Oscillating U-tube Densitometry | Measures resonant frequency shift of a vibrating U-shaped tube filled with sample, correlated to density. |
| Refractive Index at 20 °C | Digital Refractometry | Determines refractive index via critical angle measurement of light passing through the sample. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation & Weighing) | Sample is evaporated to dryness under controlled conditions; residue mass is measured relative to initial sample mass. |
| Sulfur Content | Combustion IC (Ion Chromatography after oxidative combustion) | Organic sulfur is oxidized to sulfate, then quantified as SO₄²⁻ via suppressed conductivity detection. |
| Odor Impurities (e.g., methyl mercaptan) | GC-SCD (Gas Chromatography–Sulfur Chemiluminescence Detection) | Selective detection of sulfur-containing volatile impurities based on chemiluminescent emission from SO*. |
