Manufacturing Quality Control of Isopropylsulfonamide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area against calibrated standard. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separates and quantifies impurities based on differential retention and UV absorbance. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, and sulfur dioxide in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue after controlled high-temperature ashing. |
| Heavy Metals | ICP-OES | Quantifies metallic impurities (e.g., Pb, Cd, Hg, As) by atomic emission intensity of plasma-excited elements. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and detects chloride ions based on anion exchange and conductivity detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity using calibrated glass electrode and reference electrode. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against defined standards under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using capillary tube and calibrated thermometer. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light induced by chiral molecules in solution. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Quantifies volatile organic solvents by GC analysis of vapor phase above sample solution. |
