Manufacturing Quality Control of 4-N-PROPYLBENZENESULFONYL CHLORIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separates and quantifies impurities based on differential retention and UV absorbance at 254 nm. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling | Detects and quantifies volatile organic solvents using partition equilibrium and flame ionization detection. |
| Moisture Content | Karl Fischer Titration | Measures water content via stoichiometric reaction between iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Determines acidic impurities by titration with standardized sodium hydroxide using phenolphthalein indicator. |
| Chloride Content | Potentiometric Titration with AgNO3 | Quantifies chloride ions by precipitation titration monitored with silver indicator electrode. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Multi-element detection of trace metals after acid digestion and plasma excitation. |
| Sulfate Residue | Gravimetric Analysis | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid under controlled heating rate. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under standardized lighting and conditions. |
| Bulk Density | Graduated Cylinder Method | Determines mass per unit volume of freely settled powder in a calibrated cylinder. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution by analyzing angular scattering pattern of laser beam passing through dispersed sample. |
