Manufacturing Quality Control of Methyl toluenesulfonate
| 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 under validated chromatographic conditions. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine reacts stoichiometrically with water; endpoint detected by current change. |
| Residue on Ignition | Gravimetric analysis after high-temperature ashing | Mass of non-volatile inorganic residue determined after incineration at 700–800 °C. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Multi-element detection via atomic emission from plasma-excited atoms; quantification using calibration curves. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation of anions on ion-exchange column followed by quantitative detection based on electrical conductivity. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of acidic impurities (e.g., residual sulfonic acid) using standardized sodium hydroxide and potentiometric endpoint detection. |
| Appearance & Color | Visual inspection against APHA/Pt-Co scale | Comparison of sample solution clarity and yellowness to standardized platinum-cobalt color solutions under controlled lighting. |
| Melting Point | Capillary melting point apparatus | Determination of temperature range at which solid transitions to liquid, indicating purity and identity via deviation from literature value (52–54 °C). |
