Manufacturing Quality Control of Chlorohydroquinone
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Loss on Drying | Gravimetric (105 C, 2 h) | Measurement of mass loss after drying under controlled temperature and time to determine volatile content including moisture and solvents. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of water with iodine and sulfur dioxide in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric (550 C) | Determination of non-volatile inorganic impurities by ignition of sample at high temperature and weighing residual ash. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption spectroscopy measuring absorbance of ground-state atoms in flame or graphite furnace, calibrated with lead standards. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with conductivity detection. |
| Sulfate Impurity | Turbidimetry | Formation of barium sulfate precipitate in acidic medium; turbidity measured spectrophotometrically at 420 nm. |
| Related Substances | HPLC-DAD | Identification and quantification of structurally related impurities using HPLC with diode-array detection and reference standards. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range over which solid transforms to liquid. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of hydrogen ion activity in a saturated aqueous suspension using calibrated pH electrode and meter. |
| Organic Volatile Impurities | GC-FID | Separation and quantification of residual solvents using gas chromatography with flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity pattern to calculate particle size distribution in dispersed dry or wet sample. |
