Industrial Applications of 2432-42-0
| Industry | Application | Process |
|---|---|---|
| Pesticides | Synthesis of organic sulfur pesticide intermediates | Used as S-ethyl thiopropionate in esterification and substitution reactions to prepare sulfur-containing heterocycles or thioether-based insecticides and fungicides |
| Pharmaceuticals | Synthesis of sulfur-containing drug intermediates | Applied in constructing sulfur-containing functional groups in drug molecules, such as precursors for antibiotics or antitumor compounds |
| Chemical Synthesis | Organic synthesis intermediate | Employed as a nucleophile or sulfur source in C–S bond-forming reactions to synthesize thioesters and thioethers |
Manufacturing Quality Control of 2432-42-0
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component using retention time and peak area calibration against reference standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralizes acidic impurities; endpoint detected potentiometrically or with phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Compares sample color to platinum-cobalt standard scale using APHA color units. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube) | Determines density from resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 degC | Abbe Refractometer | Measures refractive index based on critical angle of total internal reflection at prism-sample interface. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates known volume to dryness and weighs non-volatile residue after controlled heating. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies trace metals by measuring absorption of characteristic wavelength light by ground-state atoms in flame. |
| Sulfur Content | Combustion IC (Ion Chromatography after oxidation) | Oxidizes organic sulfur to sulfate, then quantifies sulfate ion via conductivity detection. |
| Volatility Residue | Thermogravimetric Analysis (TGA) | Measures mass loss under controlled heating to assess non-volatile contaminants. |
| Odor Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies volatile odor-active impurities by retention time and mass spectral matching. |
| Specific Optical Rotation | Polarimeter | Measures rotation of plane-polarized light caused by chiral compounds in solution at specified concentration and path length. |
