| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates Synthesis | Oxidant for asymmetric epoxidation to produce chiral pharmaceutical intermediates, such as β-blockers | Stereoselective epoxidation of olefin substrates in dichloromethane at 0–5°C |
| Fine Chemicals | Selective oxidation of allylic alcohols to produce high-purity epoxy alcohols | Oxidation under anhydrous conditions in acetonitrile, with pH controlled at 7–8 to prevent over-oxidation |
| Materials Science | Component of polymerization initiators for low-temperature curing of unsaturated polyester resins | Free-radical polymerization initiation in synergy with tertiary amines at ambient temperature to 40°C, reducing gel time |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Mg(C6H4(CO2)2O)2.6H2O) | Redox Titration with KMnO4 | Oxidation of peroxide moiety by standardized KMnO4 in acidic medium; endpoint detected by persistent pink color. |
| Moisture Content | Karl Fischer Titration | Quantitative reaction of water with iodine and sulfur dioxide in pyridine/methanol medium; coulometric or volumetric detection. |
| Magnesium Content | EDTA Complexometric Titration | Chelation of Mg2+ with standardized EDTA at pH 10; endpoint detected using Eriochrome Black T indicator. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element detection via ionization in plasma and mass spectrometric separation; ultra-trace quantification. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Precipitation of Cl- as AgCl; endpoint determined by silver ion-selective electrode potential shift. |
| Sulfate Impurity | Gravimetric Analysis | Precipitation as BaSO4 under controlled acidity and temperature; dried and weighed as pure sulfate salt. |
| pH of Aqueous Suspension | pH Meter Measurement | Electrochemical measurement of H+ activity in a defined suspension (e.g., 1% w/v in CO2-free water) at 25 C. |
| Organic Impurities (Phthalic Acid, etc.) | HPLC-UV | Separation on reversed-phase C18 column; UV detection at 220-230 nm based on absorbance of aromatic carboxylates. |
| Peroxide Value | Iodometric Titration | Reaction of peroxide with excess KI under acidic conditions to liberate I2; titrated with Na2S2O3 using starch indicator. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles in liquid medium to calculate size distribution by Mie theory. |
| Bulk Density | Tap Density Measurement | Mass of sample divided by volume after standardized tapping (ASTM D1895); measures flowability and packing behavior. |
| Thermal Stability (Onset Decomposition) | TGA | Measurement of mass loss versus temperature under controlled atmosphere (e.g., N2); identifies decomposition onset and profile. |
