Manufacturing Quality Control of 2,4-Dimethylaniline hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with NaOH | Quantifies the salt content by titrating the protonated amine with standardized sodium hydroxide using an indicator or potentiometric endpoint. |
| Loss on Drying (LOD) | Gravimetric Analysis (Thermogravimetry) | Measures mass loss after drying at specified temperature (e.g., 105 °C) to determine volatile impurities and residual moisture. |
| Residue on Ignition | Gravimetric Ashing | Determines inorganic residue after high-temperature incineration (e.g., 600–800 °C), indicating inorganic contaminants or metal salts. |
| Heavy Metals (as Pb) | Colorimetric Sulfide Precipitation (USP <231>) | Forms colored metal sulfide complexes under controlled pH; compared visually or spectrophotometrically against lead standard. |
| Chloride Impurity | Potentiometric Titration with AgNO₃ | Measures chloride ions via argentometric titration using silver nitrate and a silver indicator electrode. |
| Related Substances | HPLC-UV | Separates and quantifies structurally related impurities (e.g., unreacted 2,4-xylidine, oxidation products) using reversed-phase chromatography and UV detection. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid-to-liquid phase transition occurs, indicating purity and identity. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemically determines trace water content via iodine generation and stoichiometric reaction with water. |
| Sulfated Ash | Gravimetric Ashing with H₂SO₄ Pretreatment | Quantifies non-volatile inorganic residue after sulfuric acid digestion and high-temperature ashing. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to detect chiral impurities or confirm enantiomeric purity (though compound is achiral, used for consistency). |
