Manufacturing Quality Control of 2-Naphthylhydrazine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against a certified reference standard. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water; endpoint detected potentiometrically. |
| Residue on Ignition | Gravimetric Analysis | Heating sample at 750 C to constant weight and measuring non-volatile inorganic residue as mass percentage. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion, based on atomic emission intensities at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column followed by suppressed conductivity detection. |
| Sulfate Impurity | Turbidimetry | Precipitation of sulfate as barium sulfate in acidic medium; quantification via light scattering measurement. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition temperature using calibrated capillary tube method per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light and against standard references. |
| Solubility in Water | Qualitative Solubility Test | Observation of complete dissolution of specified amount in defined volume of distilled water at 25 C with agitation. |
| Related Substances | HPLC-DAD | Identification and quantification of structurally similar impurities using HPLC with diode-array detection and retention time/spectral matching. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of hydrogen ion activity in a saturated aqueous suspension using calibrated glass electrode. |
| Organic Volatile Impurities | GC-FID | Separation and quantification of residual solvents using gas chromatography with flame ionization detection. |
