Manufacturing Quality Control of ANTHRAQUINONE-2,7-DISULFONIC ACID DISODIUM SALT
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies active compound concentration based on absorbance at characteristic wavelength (e.g., ~254 nm) using Beer-Lambert law. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration with iodine, where water reacts stoichiometrically with iodine and sulfur dioxide in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measures inorganic ash content by ignition at 700-800 C and weighing residual inorganic matter after organic volatilization. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 under acidic conditions; mass of dried precipitate correlates to sulfate content. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomizing sample in flame/graphite furnace and measuring absorption of specific elemental wavelengths. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated glass electrode and reference electrode in aqueous solution. |
| Organic Impurities (Related Substances) | High Performance Liquid Chromatography (HPLC) | Separates and quantifies structurally related impurities using reversed-phase C18 column and UV detection. |
| Sodium Content | Flame Photometry | Measures sodium ion emission intensity at characteristic wavelength (589 nm) in oxidizing flame. |
| Iron Impurity | ICP-OES | Quantifies iron via plasma-induced atomic emission at element-specific wavelength after acid digestion. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying | Measures weight loss after heating at 105 C for specified time, reflecting volatile components including residual solvents and moisture. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular variation in laser light scattering pattern of dispersed particles in liquid or air. |
