Manufacturing Quality Control of 4-BROMOBENZENESULFONIC ACID MONOHYDRATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Water Content | Karl Fischer Titration | Electrochemical titration based on the reaction of iodine with water in a methanol-based reagent, measuring endpoint potentiometrically. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C to combust organic matter, then weighing inorganic residue after cooling in a desiccator. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion by measuring absorbance of ground-state atoms in flame or graphite furnace. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Titration with silver nitrate using a silver indicator electrode; endpoint detected by abrupt potential change due to AgCl precipitation. |
| Sulfate Impurity | Gravimetric Analysis (BaSO4) | Precipitation of sulfate as barium sulfate in acidic medium, followed by filtration, drying, and weighing of the precipitate. |
| Melting Point | Capillary Melting Point Determination | Measurement of temperature range over which solid transitions to liquid using calibrated capillary apparatus under controlled heating rate. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separation and quantification of residual solvents and volatile organics using capillary column and flame ionization detection. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of visible particulates or discoloration against white background under controlled lighting. |
| Acidity (Free Acid) | Acid-Base Titration | Neutralization of free sulfonic acid groups with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to calculate volume-based particle size distribution in dispersed suspension. |
| Bulk Density | Graduated Cylinder Method | Measurement of mass per unit volume of freely settled powder in a calibrated cylinder after gentle tapping to standardize packing. |
