Manufacturing Quality Control of BROMOPHENOL BLUE SODIUM SALT
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Measures absorbance at characteristic wavelength (e.g., 590 nm) and calculates concentration using Beer-Lambert law and certified reference standard. |
| Loss on Drying | Gravimetric Analysis (Thermogravimetry) | Determines volatile content by measuring mass loss after drying at specified temperature (e.g., 105 C) for fixed duration. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Quantifies inorganic impurities by ignition of sample to constant weight after sulfuric acid treatment. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures total heavy metal content via flame or graphite furnace AAS after acid digestion and chelation. |
| Chloride Impurity | Potentiometric Titration | Titrates chloride ions with silver nitrate using silver indicator electrode; endpoint detected by potential change. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 under controlled conditions and determines mass after filtration and drying. |
| pH of Aqueous Solution | pH Potentiometry | Measures hydrogen ion activity in saturated aqueous solution using calibrated pH electrode. |
| Melting Point | Capillary Melting Point Determination | Observes temperature range over which solid transitions to liquid using calibrated capillary apparatus. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and quantifies residual solvents using flame ionization detection with internal standard calibration. |
| Related Substances | High Performance Liquid Chromatography (HPLC-UV) | Separates and detects structurally related impurities using reversed-phase column and UV detection at 254/590 nm. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemically determines water content based on stoichiometric iodine generation and reaction with water. |
| Bulk Density | Volumetric Method (ASTM D1895) | Measures mass per unit volume of freely settled powder in standardized cylinder under controlled tapping. |
