Manufacturing Quality Control of 2-Chloro-1,4-phenylenediamine sulfate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and peak area normalization. |
| Loss on Drying | Gravimetric method | Measurement of mass loss after drying under specified temperature and vacuum conditions to determine volatile content. |
| Residue on Ignition | Sulfated ash gravimetry | Conversion of organic matter to sulfate ash by controlled combustion, followed by weighing of inorganic residue. |
| Chloride Content | Potentiometric titration with AgNO3 | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| Sulfate Content | Gravimetric analysis with BaCl2 | Precipitation of sulfate as barium sulfate, followed by filtration, ignition, and weighing of the dried precipitate. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption spectroscopy after acid digestion and matrix matching; measures total extractable heavy metals relative to lead standard. |
| Iron Content | AAS (Flame) | Determination of iron concentration via flame atomic absorption at 248.3 nm after sample dissolution and appropriate dilution. |
| Water Content | Karl Fischer titration | Volumetric or coulometric titration based on iodine consumption in a reaction specific to water in anhydrous methanol-based reagent. |
| pH of Aqueous Solution | pH meter measurement | Direct potentiometric measurement of pH in a defined aqueous suspension (e.g., 1% w/v) at 25 C using calibrated pH electrode. |
| Particle Size Distribution | Laser diffraction | Analysis of scattered laser light intensity vs. angle to calculate particle size distribution in dispersed solid sample. |
| Microbial Contamination | Plate count method | Enumeration of aerobic mesophilic microorganisms by membrane filtration or pour plate technique on TSA medium, incubated at 30-35 C for 3-5 days. |
