Manufacturing Quality Control of 12217-79-7
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at characteristic wavelength. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration with iodine-based reagent. |
| Ash Content | Gravimetric Analysis | Determines inorganic residue after high-temperature incineration and weighing. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Quantifies total heavy metals by atomic absorption of ground-state atoms in flame or graphite furnace. |
| Chloride Content | Potentiometric Titration | Measures chloride ions using silver nitrate titrant and silver-sulfide indicator electrode. |
| pH of Aqueous Solution | pH Meter Measurement | Determines hydrogen ion activity in 1% aqueous dispersion using calibrated glass electrode. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution based on angular variation of scattered laser light intensity. |
| Water Solubility | Gravimetric Filtration | Determines insoluble fraction after stirring in distilled water, hot filtration, and drying. |
| Organic Impurities (Related Substances) | HPLC-DAD | Detects and quantifies structurally related impurities using diode array detection with gradient elution. |
| Bulk Density | Tap Density Measurement | Measures mass per unit volume after standardized tapping of a known powder mass in a graduated cylinder. |
| Color Strength (Tinting Strength) | Reflectance Spectrophotometry | Compares color intensity relative to standard via Kubelka-Munk transformed reflectance at lambda max. |
| Thermal Stability | TGA | Evaluates weight loss profile under controlled nitrogen atmosphere to assess decomposition onset temperature. |
