Manufacturing Quality Control of 6-CHLORO-2-AMINOPHENOL-4-SULFONIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content based on the stoichiometric reaction of iodine with water in pyridine-methanol medium. |
| 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) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion by measuring absorbance of ground-state atoms in flame or graphite furnace. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Titration with silver nitrate using silver indicator electrode; endpoint detected by abrupt potential change due to AgCl precipitation. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitation of sulfate as BaSO4 in acidic medium, followed by filtration, drying, and weighing of the precipitate. |
| Related Substances | HPLC-DAD | Separation and detection of structurally related impurities using HPLC with diode-array detection for spectral confirmation and quantification. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measurement of hydrogen ion activity in a 1% w/v aqueous suspension using calibrated glass electrode and pH meter. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, observed visually under controlled heating rate. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separation and quantification of residual solvents using capillary GC with flame ionization detection. |
| Iron Content | Colorimetric Spectrophotometry (1,10-Phenanthroline) | Reduction of Fe3+ to Fe2+, complexation with 1,10-phenanthroline, and measurement of absorbance at 510 nm. |
| Bulk Density | Graduated Cylinder Method | Mass of sample poured into standardized cylinder divided by its settled volume, measured under defined tapping conditions. |
