Industrial Applications of METHYL-(3-HYDROXYPROPYL) SULFONE
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Intermediate | Used as an intermediate in the synthesis of methanesulfonyl-containing antibiotics (e.g., thiamphenicol), where the alcohol hydroxyl group participates in esterification or etherification to construct the molecular scaffold |
| Pesticides | Intermediate | Applied as a synthetic intermediate for sulfur-containing heterocyclic or sulfone pesticides, enabling nucleophilic substitution or oxidation to introduce the methanesulfonyl group |
| Chemical Synthesis | Organic Synthesis Intermediate | Employed in the preparation of functionalized alcohol derivatives, participating in multistep syntheses of complex molecules via oxidation, substitution, or protecting-group strategies |
Manufacturing Quality Control of METHYL-(3-HYDROXYPROPYL) SULFONE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration standard using internal or external standardization. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by ashing sample at 700-800 C and weighing residual mass. |
| Acidity (as H2SO4) | Acid-Base Titration | Titration with standardized NaOH solution using phenolphthalein indicator to quantify acidic impurities. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies metal impurities (e.g., Pb, Cd, Fe) after acid digestion by measuring element-specific atomic absorption. |
| Chloride Content | Potentiometric Titration with AgNO3 | Measures chloride ions via precipitation titration with silver nitrate and silver indicator electrode. |
| Sulfate Content | Barium Sulfate Gravimetric Method | Precipitates sulfate as BaSO4 in acidic medium and determines mass after filtration and drying. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color intensity against platinum-cobalt standard solutions at 455 nm. |
| Specific Gravity | Digital Density Meter | Measures density relative to water at 20 C using oscillating U-tube principle. |
| Refractive Index | Refractometry | Determines ratio of light velocity in air vs. sample at 20 C using critical angle measurement. |
| Non-Volatile Residue | Evaporation and Weighing | Evaporates known volume under controlled conditions and weighs residue after drying at 105 C. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separates and quantifies structurally related impurities using reversed-phase column and UV absorbance at 220 nm. |
