Manufacturing Quality Control of 2,5-Dimethylbenzenesulfonic acid dihydrate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies sulfonic acid groups by titration with standardized NaOH solution using phenolphthalein indicator. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric reaction between iodine and water in a methanol-based reagent. |
| Loss on Drying | Gravimetric Analysis | Determines volatile content by measuring mass loss after drying at 105 C for 2 hours under controlled conditions. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring absorbance of atomic vapor at characteristic wavelengths. |
| Sulfate Impurity | Ion Chromatography (IC) | Separates and quantifies sulfate anions using anion-exchange column and conductivity detection. |
| Chloride Impurity | Potentiometric Titration | Measures chloride ions by titration with AgNO3 using silver indicator electrode and reference electrode. |
| Iron (Fe) Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Detects Fe after acid digestion by measuring intensity of emitted light at specific atomic emission lines. |
| pH of Aqueous Solution | pH Meter Measurement | Determines acidity of a standardized aqueous suspension (1% w/v) using calibrated glass electrode pH meter. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after incineration at 800 C for 30 minutes. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles against standard white background under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method. |
| Organic Impurities (Related Substances) | High Performance Liquid Chromatography (HPLC) | Separates and quantifies structurally related impurities using reversed-phase C18 column and UV detection at 254 nm. |
