Manufacturing Quality Control of Ethanesulfonic acid isopropyl ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a calibrated column and flame ionization detector. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in anhydrous methanol/pyridine medium, detecting endpoint amperometrically. |
| Residue on Ignition | Gravimetric Analysis | Sample is ignited at 700-800 C to combust organic matter; residual inorganic ash is weighed after cooling in a desiccator. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein indicator; calculated as sulfuric acid equivalent. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification by measuring metal ion signals after plasma ionization and mass separation under high vacuum. |
| Chloride Impurity | Ion Chromatography (IC) | Separation of chloride anions on an anion-exchange column followed by conductivity detection and quantification against calibration standards. |
| Sulfate Impurity | Ion Chromatography (IC) | Anion separation and conductivity-based quantification of sulfate ions using suppressed IC with carbonate/bicarbonate eluent. |
| Appearance | Visual Inspection | Assessment of liquid clarity and color against water-white standard under controlled white light and specified viewing conditions. |
| Density | Digital Density Meter | Measurement of sample density at 20 C using oscillating U-tube principle with temperature-controlled Peltier system. |
| Refractive Index | Refractometry | Determination of refractive index at 20 C using Abbe refractometer or digital equivalent based on critical angle of total internal reflection. |
| Volatile Impurities | Headspace GC-MS | Identification and quantification of low-boiling impurities via gas-phase sampling from sealed vials followed by capillary GC separation and mass spectral detection. |
| Related Substances | HPLC with UV Detection | Separation of structurally related compounds on reversed-phase C18 column with gradient elution and UV detection at 210 nm. |
