Manufacturing Quality Control of 3-METHOXYSULFOLANE
| 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 a methanol-based reagent; endpoint detected amperometrically. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a known sample mass to dryness at 105 C, followed by weighing of non-volatile residue. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Comparison of sample color against APHA platinum-cobalt standard solutions at 455 nm using calibrated color scale. |
| Density at 20 C | Digital Density Meter | Measurement of sample density via oscillating U-tube principle with temperature-controlled Peltier element. |
| Refractive Index at 20 C | Refractometry | Determination of refractive index by measuring critical angle of total internal reflection using a calibrated Abbe refractometer. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride anions on an anion-exchange column with suppressed conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after wet digestion, using air-acetylene flame and lead-specific hollow cathode lamp. |
| Non-Volatile Residue | Gravimetric Analysis | Evaporation of specified volume to dryness at 105 C, followed by drying to constant weight and mass determination. |
| Aldehyde Impurity | UV-Vis Spectrophotometry | Derivatization with 2,4-dinitrophenylhydrazine followed by measurement of hydrazone absorbance at ~450 nm. |
| Sulfone Impurity | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation by GC followed by identification and quantification using characteristic mass fragments and selected ion monitoring. |
