Manufacturing Quality Control of 2-Nitrophenylhydrazine hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at ~300 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., 2-nitroaniline, hydrazine hydrochloride) using gradient HPLC with UV detection. |
| Loss on Drying | Gravimetric (Oven Drying) | Mass loss measured after drying at 105 C for 2 hours under controlled humidity and atmospheric pressure. |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Mass of non-volatile inorganic residue remaining after high-temperature incineration (~700 C) following sulfuric acid treatment. |
| Chloride Content | Potentiometric Titration with AgNO3 | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Quantification of total heavy metals by atomic absorption spectroscopy after wet digestion and matrix-matched calibration. |
| Iron (Fe) Content | AAS | Direct measurement of iron concentration using atomic absorption spectroscopy at 248.3 nm after acid dissolution. |
| Sulfate (SO4) Content | Gravimetric (Barium Sulfate Precipitation) | Precipitation of sulfate as BaSO4 followed by filtration, drying, and weighing of the ignited precipitate. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Measurement of hydrogen ion activity in a 1% w/v aqueous suspension using a calibrated glass electrode pH meter. |
| Water Content (Karl Fischer) | Coulometric Karl Fischer Titration | Electrochemical generation and reaction of iodine with water in anhydrous methanol-based reagent; water quantified by charge consumed. |
| Organic Volatile Impurities | GC-FID | Detection and quantification of residual solvents (e.g., methanol, acetone) using capillary gas chromatography with flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity versus angle to determine volume-based particle size distribution in dispersed dry powder. |
