Industrial Applications of METHYL PHENYL SULFOXIDE
| Industry | Application | Process |
|---|---|---|
| Chemical Intermediates | Intermediate in the synthesis of pharmaceuticals and agrochemicals | Oxidation of toluene with sulfur dioxide under catalytic conditions to produce methyl phenyl sulfoxide |
| Pharmaceutical R&D | Precursor for synthesizing sulfur-containing drugs | Used in organic synthesis to construct specific sulfur-containing heterocyclic structures, enhancing the biological activity of drug molecules |
| Materials Science | Functional additive for material modification | Introduced as a polar group into polymeric materials to improve thermal stability and solubility |
| High-Purity Reagents | Used as analytical reference standards or reaction reagents in laboratories | Purified via recrystallization, distillation, and other techniques to obtain high-purity product for precision chemical experiments |
Manufacturing Quality Control of METHYL PHENYL SULFOXIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies methyl phenyl sulfoxide by separation on a capillary column and flame ionization detection relative to an internal standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine generated electrochemically or added stoichiometrically in pyridine/methanol solvent. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by incinerating sample at 700-800 C and weighing the residual ash. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals (e.g., Pb, Cd, Hg, As) after acid digestion by measuring atomic absorption at element-specific wavelengths. |
| Chloride Content | Potentiometric Titration with Silver Nitrate | Measures chloride ions by titration with AgNO3 using a silver indicator electrode; endpoint detected by potential change. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Evaluates color intensity by comparing sample solution to APHA platinum-cobalt standard solutions at 455 nm. |
| Density at 20 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle calibrated with air and water standards. |
| Refractive Index at 20 C | Abbe Refractometer | Determines refractive index by measuring critical angle of total internal reflection of sodium D-line light. |
| Non-Volatile Matter | Gravimetric Evaporation | Quantifies residue after evaporating a known volume at 105 C under controlled airflow and weighing dried residue. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separates and quantifies structurally related impurities (e.g., methyl phenyl sulfide, sulfone) using reversed-phase C18 column and UV absorbance at 254 nm. |
| Sulfur Content | Combustion IC (Ion Chromatography after Combustion) | Oxidizes organic sulfur to sulfate, then quantifies sulfate ion via suppressed conductivity detection in ion chromatography. |
