Manufacturing Quality Control of 1-chloro-2-naphthol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 280 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching with reference standards or relative response factors. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent; water reacts stoichiometrically to generate endpoint current or color change. |
| Residue on Ignition | Gravimetric Analysis | Heating sample at 700-800 C to constant weight; residue mass expressed as percentage of original sample. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption spectroscopy after acid digestion; quantifies metal content via absorbance of ground-state atoms in flame or graphite furnace. |
| Chloride Impurity | Ion Chromatography | Separation of anions on ion-exchange column with conductivity detection; chloride quantified using external calibration curve. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as solid-to-liquid phase change; reported as onset and clear point. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against standard white background under controlled lighting. |
| Solubility in Common Solvents | Qualitative Solubility Test | Observation of complete dissolution in specified solvents (e.g., ethanol, acetone, toluene) at room temperature. |
| pH of Aqueous Suspension | pH Meter Measurement | pH measured in 1% w/v aqueous suspension using calibrated pH electrode; reflects acidic character due to phenolic OH group. |
| Volatile Impurities | GC-FID | Separation by gas chromatography with flame ionization detection; semi-quantitative screening for low-boiling organic contaminants. |
| Sulfated Ash | Gravimetric Analysis | Sample treated with sulfuric acid, then ignited at 600-700 C; residual sulfate ash weighed and expressed as percentage. |
