Manufacturing Quality Control of BASIC RED 29
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 530 nm based on peak area comparison against certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities by retention time and peak area relative to main peak using gradient elution. |
| Loss on Drying | Gravimetric Method | Measures mass loss after drying at 105 C for 2 hours; reflects volatile content including residual solvents and moisture. |
| Residue on Ignition | Sulfated Ash Method | Determines inorganic residue after controlled ignition at 600 C; indicates presence of metallic salts or inorganic contaminants. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Quantifies total heavy metals by atomic absorption spectroscopy after acid digestion and chelation with dithizone. |
| Chloride Content | Potentiometric Titration | Measures chloride ions via titration with silver nitrate using silver indicator electrode and reference electrode. |
| Sulfate Content | Gravimetric Method | Precipitates sulfate as barium sulfate under acidic conditions and determines mass after filtration and drying. |
| pH (1% aqueous solution) | pH Meter Measurement | Measures hydrogen ion activity in a standardized 1% w/v aqueous suspension using calibrated pH meter with glass electrode. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration with iodine generated electrochemically in methanol-based reagent. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution by measuring angular variation in laser light scattering from dispersed particles in liquid medium. |
| Color Value (APHA) | Visual Comparison or Spectrophotometer | Evaluates color intensity by matching sample solution to APHA platinum-cobalt standards or measuring absorbance at 430 nm. |
| Organic Volatile Impurities | GC-FID | Identifies and quantifies residual solvents (e.g., methanol, acetone) using gas chromatography with flame ionization detection. |
