Manufacturing Quality Control of Methyl methanesulfonate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard using a polar capillary column. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in anhydrous methanol/pyridine medium. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled high-temperature ashing at 500-600 C. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after wet digestion, based on absorption of characteristic atomic spectral lines. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using an anion-exchange column and conductivity detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitation of sulfate as BaSO4 under controlled acidic conditions followed by drying and weighing. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Comparison of sample color intensity against platinum-cobalt standard solutions at 455 nm wavelength. |
| Density at 20 C | Digital Density Meter | Measurement of mass per unit volume using oscillating U-tube principle calibrated with air and water standards. |
| Refractive Index at 20 C | Refractometry | Determination of light bending angle at air-sample interface using calibrated Abbe refractometer. |
| Boiling Point | Distillation with Digital Thermometer | Measurement of temperature at which vapor pressure equals atmospheric pressure during controlled atmospheric distillation. |
| Organic Volatile Impurities | Headspace Gas Chromatography-Mass Spectrometry (HS-GC-MS) | Identification and quantification of residual solvents via thermal equilibrium headspace sampling and mass spectral detection. |
