Manufacturing Quality Control of Ethyl p-toluenesulfonate
| 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 non-polar capillary column. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water in the sample. |
| 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 (Weight Loss on Ignition) | Sample is ignited at 700-800 C and residue mass is measured after cooling in a desiccator. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals by atomization in flame or graphite furnace and absorption measurement at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using an anion-exchange column and conductivity detection. |
| Sulfate Impurity | Barium Chloride Turbidimetry | Precipitation of sulfate as barium sulfate; turbidity measured spectrophotometrically at 420 nm. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against a white background under controlled lighting. |
| Melting Point | Capillary Melting Point Determination | Thermal transition observed as solid-to-liquid phase change using calibrated melting point apparatus. |
| Organic Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Volatile residual solvents are equilibrated in headspace vial and analyzed by GC-FID. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of structurally related impurities using reversed-phase C18 column and UV absorbance at 254 nm. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution of the compound in a specified solvent and path length. |
