Manufacturing Quality Control of Methanedisulfonic acid dipotassium salt
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies active ingredient by titration with standardized HCl using bromocresol green indicator. |
| Moisture Content | Karl Fischer Titration | Measures water content via iodine-sulfur dioxide redox reaction in methanol-based reagent. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Determines trace heavy metals by measuring absorbance of ground-state atoms in flame or graphite furnace. |
| Chloride Impurity | Potentiometric Titration | Detects chloride ions using silver nitrate titrant and silver/silver chloride reference electrode. |
| Sulfate Impurity | Gravimetric Analysis | Precipitates sulfate as barium sulfate, followed by drying and weighing of the precipitate. |
| pH (1% aqueous solution) | pH Meter Measurement | Measures hydrogen ion activity in a standardized aqueous solution using calibrated glass electrode. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by ignition at 700-800 C and weighing residue. |
| Iron (Fe) Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies elemental iron by measuring characteristic atomic emission lines after plasma atomization. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or discoloration under controlled lighting. |
| Particle Size Distribution | Laser Diffraction | Measures particle size by analyzing angular variation in intensity of laser light scattered by dispersed particles. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Determines volatile content by measuring mass loss upon heating to 105 C under controlled atmosphere. |
| Organic Impurities | High Performance Liquid Chromatography (HPLC) | Separates and quantifies organic impurities using reversed-phase column and UV detection at 210 nm. |
