Manufacturing Quality Control of 4-FLUOROBENZOIC ANHYDRIDE
| 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 solvent system. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C to volatilize organic matter, then weighing inorganic residue. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element detection after acid digestion, quantifying metals via atomic emission intensity at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Related Substances | HPLC-DAD | Identification and quantification of structurally similar impurities using diode-array detection and retention time matching. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change in a capillary tube under controlled heating rate. |
| Acid Value | Acid-Base Titration | Neutralization of acidic groups with standardized KOH ethanol solution using phenolphthalein indicator. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against established reference standards under controlled lighting. |
| Residual Solvents | GC-FID | Separation and quantification of volatile solvents using gas chromatography with flame ionization detection. |
| Sulfated Ash | Gravimetric Analysis | Combustion with sulfuric acid followed by high-temperature ashing and residue weighing. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine size distribution of dry or dispersed particles. |
