Manufacturing Quality Control of BASIC RED 46
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies dye concentration based on absorbance at λmax (≈520 nm) using a calibrated standard curve in aqueous alkaline medium. |
| Heavy Metals (as Pb) | ICP-OES | Simultaneously detects and quantifies trace metal impurities (e.g., Pb, Cd, Cr, Ni) after acid digestion by measuring element-specific emission intensities. |
| Water Content | Karl Fischer Titration | Determines water content via stoichiometric iodine–sulfur dioxide reaction in anhydrous methanol/pyridine medium. |
| pH of Aqueous Solution (1% w/v) | pH Potentiometry | Measures hydrogen ion activity using a calibrated glass electrode in a standardized aqueous dispersion. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Quantifies non-volatile inorganic impurities by weighing residue remaining after high-temperature (550–600 °C) ignition. |
| Chloride Content | Potentiometric Titration with AgNO3 | Determines chloride ions by titration with silver nitrate, monitored via silver-ion-selective electrode endpoint detection. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related impurities (e.g., intermediates, isomers, degradation products) using reversed-phase C18 column and UV detection at 254/520 nm. |
| Particle Size Distribution | Laser Diffraction | Measures volumetric particle size distribution in aqueous suspension by analyzing angular scattering pattern of laser light. |
| Bulk Density | ASTM D1895 (Method A) | Determines mass per unit volume of freely settled powder using a standardized graduated cylinder and controlled tapping procedure. |
| Color Strength (Relative to Standard) | UV-Vis Spectrophotometry | Compares absorbance ratio of sample vs. certified reference standard under identical dilution and pH conditions to assess batch-to-batch color intensity consistency. |
