Manufacturing Quality Control of ASTRAZON BRILLIANT RED 4G
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies dye concentration based on absorbance at characteristic lambda-max in standardized solvent system using Beer-Lambert law. |
| Moisture Content | Karl Fischer Titration | Determines water content via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Inorganic Salt (Na2SO4) | Gravimetric Analysis | Precipitates sulfate as BaSO4 after acid digestion and measures mass of dried precipitate. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously quantifies trace metals after acid digestion by measuring element-specific emission intensities in plasma. |
| pH of 1% Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity using calibrated glass electrode in standardized aqueous dispersion. |
| Water Solubility | Visual Dissolution Test | Evaluates complete dissolution in distilled water at specified temperature and time under controlled agitation. |
| Residue on Ignition | Gravimetric Ash Test | Determines non-volatile inorganic residue after high-temperature incineration at 500-600 C. |
| Chloride Content | Argentometric Titration (Mohr method) | Titrates chloride with standard AgNO3 solution using K2CrO4 indicator; endpoint signaled by red Ag2CrO4 precipitate. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related impurities using reversed-phase column and UV detection at multiple wavelengths. |
| Bulk Density | ASTM D1895 Method A | Measures mass per unit volume of freely settled powder in a standardized cylinder. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular dependence of laser light scattering from dispersed particles. |
| Color Strength (Relative to Standard) | UV-Vis Spectrophotometry | Compares absorbance ratio of sample and certified reference standard under identical conditions to determine relative dyeing power. |
