Manufacturing Quality Control of 3-Aminothiophenol
| 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 detection of impurities (e.g., 3-nitrothiophenol, disulfides, anilines) using gradient HPLC with UV detection. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generation in pyridine-methanol solvent to determine water content by stoichiometric reaction. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C to combust organic matter, then weighing inorganic residue after cooling in desiccator. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion, measuring atomic emission intensities at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation of chloride ions on an anion-exchange column with conductivity detection using sodium carbonate/bicarbonate eluent. |
| Sulfate Impurity | Ion Chromatography | Anion separation and conductivity detection following sample dissolution and filtration; sulfate elutes after chloride. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using calibrated capillary tube method per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles against standard white background under controlled lighting. |
| Solubility in Ethanol | Qualitative Solubility Test | Observation of complete dissolution of specified amount in defined volume of ethanol at 20 C with gentle agitation. |
| pH of Aqueous Solution | pH Meter | Measurement of hydrogen ion activity in saturated aqueous solution using calibrated glass electrode system. |
| Odor | Sensory Evaluation | Trained personnel assess characteristic thiol odor intensity and detect off-odors consistent with degradation or contamination. |
