Manufacturing Quality Control of 4-Chlorobenzene-1,2-diol
| 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 275 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., 4-chlorophenol, dichlorobenzenes, quinones) using gradient HPLC with UV detection. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration with iodine reagent to determine water content based on stoichiometric reaction with iodine and sulfur dioxide in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after high-temperature incineration at 700-800 C followed by weighing. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption spectroscopy quantifies total heavy metals by measuring absorbance of ground-state atoms in flame or graphite furnace atomizer. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column with suppressed conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, observed visually under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of sample against specified criteria (white to off-white crystalline powder). |
| Solubility in Water | Titrimetric or Gravimetric Solubility Test | Equilibrium solubility determined by saturation, filtration, and quantification of dissolved material via HPLC or evaporation/weighting. |
| pH of Aqueous Suspension | pH Meter Measurement | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Volatile Organic Impurities (VOIs) | GC-FID | Separation and quantification of residual solvents (e.g., methanol, acetone, toluene) using gas chromatography with flame ionization detection. |
| Sulfated Ash | Gravimetric Analysis | Weight of residue after ignition with sulfuric acid treatment, indicating inorganic sulfate-forming impurities. |
