Manufacturing Quality Control of 4-Hydrazinobenzenesulfonic acid hemihydrate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using HPLC coupled with diode-array detection; peak area comparison relative to main peak. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to quantify water content via stoichiometric redox reaction. |
| Residue on Ignition | Gravimetric Analysis | Heating sample at 700-800 C to constant weight and measuring inorganic residue as percentage of original mass. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion, based on atomic emission intensity at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation of anions on ion-exchange column with conductivity detection; quantified against chloride standard calibration curve. |
| Sulfate Impurity | Turbidimetric Method | Reaction with barium chloride under acidic conditions to form BaSO4 precipitate; turbidity measured spectrophotometrically. |
| pH of Aqueous Solution | Potentiometric Titration | Measurement of hydrogen ion activity using calibrated pH electrode in a defined aqueous suspension or solution. |
| Melting Point | Capillary Melting Point Apparatus | Thermal analysis by observing phase transition temperature range during controlled heating of capillary-packed sample. |
| Organic Volatile Impurities | GC-FID | Separation by gas chromatography followed by flame ionization detection; quantified using internal standard method. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity pattern to determine volume-based particle size distribution in dispersed suspension. |
| Bulk Density | Graduated Cylinder Method | Mass of material freely poured into a standardized cylinder divided by its settled volume, reported as g/mL. |
