Manufacturing Quality Control of Reactive Yellow 3
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison with certified reference standard using reversed-phase chromatography and UV detection at 400-420 nm. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via reaction of iodine with sulfur dioxide in a methanol-based solvent system. |
| Inorganic Salt Content | Gravimetric Analysis | Precipitation of sulfate as barium sulfate followed by filtration, drying, and weighing of the residue. |
| Heavy Metals (as Pb) | AAS | Atomic absorption spectroscopy after acid digestion and chelation; measures absorbance of ground-state atoms in flame or graphite furnace. |
| Arsenic Content | ICP-MS | Inductively coupled plasma mass spectrometry following microwave-assisted acid digestion for ultra-trace quantification. |
| pH of 1% Aqueous Solution | Potentiometric Titration | Measurement using calibrated pH electrode in aqueous suspension to assess acidity/basicity from ionizable groups. |
| Water Solubility | Visual Dissolution Test | Qualitative assessment by observing complete dissolution in distilled water at 25 C with gentle agitation over 15 minutes. |
| Residue on Ignition | Gravimetric Analysis | Heating sample at 550 C to constant weight and calculating non-volatile inorganic residue as percentage of original mass. |
| Chloride Content | Argentometric Titration | Titration with standardized silver nitrate solution using potassium chromate indicator; forms precipitate at endpoint. |
| Organic Impurities (Related Substances) | HPLC-DAD | Separation and detection of structurally related compounds using diode-array detection to compare retention times and spectra against reference standards. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern generated by dispersed particles in liquid medium to calculate size distribution profile. |
| Color Strength (K/S Value) | Reflectance Spectrophotometry | Measurement of reflectance ratio at maximum absorption wavelength relative to standard sample using Kubelka-Munk equation. |
