Manufacturing Quality Control of 2,4-Dimethylbenzenesulfonic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies active acid content by neutralization with standardized NaOH solution using phenolphthalein indicator. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric reaction between water and iodine in a pyridine-methanol solvent system. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or foreign matter against standard reference samples. |
| Melting Point | Capillary Melting Point Determination | Determines temperature range at which solid transitions to liquid using calibrated capillary apparatus per ASTM D1565. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities after high-temperature ashing and weighing of residual ash. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg) by measuring absorption of element-specific light wavelengths. |
| Sulfate Impurity | Ion Chromatography (IC) | Separates and quantifies sulfate ions based on anion exchange retention and conductivity detection. |
| Chloride Impurity | Potentiometric Titration | Detects chloride ions by titration with silver nitrate using silver electrode for endpoint detection. |
| Organic Volatile Impurities | Gas Chromatography (GC) | Identifies and quantifies residual solvents or volatile organic impurities using flame ionization detection. |
| Iron Content | Colorimetric Spectrophotometry | Measures Fe2+ complexed with 1,10-phenanthroline, quantified by absorbance at ~510 nm. |
| pH of Aqueous Solution | pH Meter Measurement | Determines acidity of saturated aqueous suspension using calibrated pH electrode per USP <791>. |
| Bulk Density | Gravimetric Volumetric Method | Calculates mass per unit volume of freely settled powder in a standardized cylinder per ASTM D1895. |
