Manufacturing Quality Control of Phenylhydrazine sulfate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (C6H8N2.H2SO4) | Acid-Base Titration with NaOH | Quantifies active ingredient by neutralizing sulfuric acid moiety using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric reaction between water, iodine, sulfur dioxide, and base in anhydrous methanol medium. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Determines total heavy metal content after acid digestion by measuring absorbance of atomic vapor at characteristic wavelength. |
| Sulfate (SO4) Content | Gravimetric Analysis | Precipitates sulfate as barium sulfate under controlled pH and temperature, then weighs dried precipitate. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities by ignition at 700-800 C and weighing residual ash. |
| Chloride (Cl) Content | Potentiometric Titration with AgNO3 | Quantifies chloride ions by titration with silver nitrate using silver electrode to detect endpoint potential change. |
| Iron (Fe) Content | ICP-OES | Determines iron concentration after acid digestion by measuring intensity of emitted light at characteristic wavelength upon plasma excitation. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in a 1% w/v aqueous suspension using calibrated glass electrode system. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles against standard reference under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per USP/EP guidelines. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies benzene derivatives and degradation products using reversed-phase column and UV detection at 254 nm. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Measures weight loss upon heating to 105 C for 2 hours, indicating volatile solvents and moisture content. |
