Manufacturing Quality Control of 5-(Chlorosulphonyl)-2-fluorobenzoic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 220-254 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of impurities using gradient HPLC-UV; identification and quantification relative to main peak. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., acetone, methanol, DMF) based on retention time and calibration curves. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Ion Chromatography (IC) | Separation and quantification of sulfate ions using anion-exchange column and conductivity detection. |
| Heavy Metals | ICP-OES | Multi-element detection after acid digestion; quantification based on characteristic atomic emission lines. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile residue remaining after high-temperature ashing at 600-750 C. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated capillary apparatus. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to calculate size distribution of dry or wet dispersed particles. |
| Bulk Density | Graduated Cylinder Method | Mass per unit volume measured by gently pouring sample into calibrated cylinder and recording settled volume. |
