Manufacturing Quality Control of 4-Methylsulphonylbenzoic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; identification by retention time matching and threshold-based reporting. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents based on calibrated external standards. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, As, Hg, and Ni after acid digestion, using plasma emission spectroscopy with matrix-matched calibration. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint determined from the inflection point in potential vs. volume curve. |
| Sulfate Content | Gravimetric Analysis | Precipitation as barium sulfate followed by high-temperature drying and weighing to determine sulfate mass fraction. |
| Water Content | Karl Fischer Titration | Coulometric or volumetric titration using iodine generated electrochemically or added reagent; water reacts stoichiometrically with iodine and sulfur dioxide in pyridine/methanol medium. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid phase transition range using calibrated capillary tube apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of color and physical state (crystalline powder) against standard white background under controlled lighting per EP 2.2.1. |
| Particle Size Distribution | Laser Diffraction | Measurement of scattered laser light intensity as a function of angle to calculate volume-based particle size distribution. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after high-temperature ashing (700-800 C) to determine inorganic non-volatile impurities. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution to confirm chiral purity and absence of racemization. |
