Manufacturing Quality Control of Ammonium 4-nitrobenzoate dihydrate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies 4-nitrobenzoic acid ammonium salt by back-titration after hydrolysis to free acid and neutralization with standardized NaOH. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric reaction between water and iodine in a methanol-based reagent. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Determines total heavy metal content by atomizing the sample and measuring absorbance of characteristic wavelengths. |
| Sulfated Ash | Gravimetric Analysis | Measures non-volatile inorganic residue after combustion with sulfuric acid followed by high-temperature ignition and weighing. |
| Chloride Impurity | Potentiometric Titration | Quantifies chloride ions using silver nitrate titrant and silver/silver chloride indicator electrode. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic impurities remaining after controlled high-temperature ignition of the sample. |
| Organic Volatile Impurities | Gas Chromatography (GC) | Separates and quantifies residual solvents or volatile organic impurities using capillary column and FID detection. |
| pH of Aqueous Solution | pH Meter Measurement | Determines acidity/basicity of a defined aqueous suspension using calibrated pH electrode. |
| Iron (Fe) Content | ICP-OES | Quantifies iron concentration by plasma excitation and measurement of emitted elemental spectral lines. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled lighting against standard reference. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution by analyzing angular variation in laser light scattering pattern. |
| Specific Optical Rotation | Polarimetry | Determines chiral purity by measuring rotation angle of plane-polarized light passing through a solution of the compound. |
