Manufacturing Quality Control of 1,2,4-Benzenetriol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | High-Performance Liquid Chromatography (HPLC) | Quantitative determination based on retention time and peak area comparison against a certified reference standard using UV detection. |
| Water Content | Karl Fischer Titration | Electrochemical titration measuring water content via iodine-sulfur dioxide reaction in a methanol-based solvent system. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measurement of non-volatile inorganic residue after controlled high-temperature ashing at 700–800 °C. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) or ICP-OES | Quantification of total heavy metals by atomization and measurement of elemental absorption/emission at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) or Potentiometric Titration | Separation and quantification of chloride ions via ion exchange chromatography or direct titration with silver nitrate using a chloride-selective electrode. |
| Related Substances | HPLC with Diode Array Detection (HPLC-DAD) | Identification and quantification of structurally related impurities (e.g., hydroquinone, catechol, benzoquinone) using retention time and spectral matching. |
| Melting Point | Capillary Melting Point Determination | Thermal transition analysis measuring the temperature range at which solid-to-liquid phase change occurs under controlled heating. |
| Sulfated Ash | Gravimetric Analysis | Determination of inorganic sulfate-derived residue after wet digestion with sulfuric acid followed by ignition and weighing. |
| Appearance (Color & Clarity) | Visual Inspection against Standard Solutions (e.g., APHA/Hazen Scale) | Subjective assessment of solution color intensity and clarity relative to platinum-cobalt reference standards in aqueous solution. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Determination of hydrogen ion activity using a calibrated glass electrode in a standardized aqueous suspension/solution. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID or GC-MS) | Separation and quantification of residual solvents (e.g., methanol, acetone, ethyl acetate) using capillary column chromatography and flame ionization/mass spectrometric detection. |
