Manufacturing Quality Control of 4-Chlorophthalic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 230-254 nm, based on peak area comparison against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., 4-chlorophthalic anhydride, phthalic acid, isomeric chlorobenzoic acids) using gradient HPLC-UV. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration with iodine reagent to determine water content based on stoichiometric reaction with iodine and sulfur dioxide in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C in a platinum crucible and weighing the non-volatile residue after complete combustion. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, Cr by plasma excitation and emission spectroscopy following acid digestion. |
| Chloride Impurity | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature range using calibrated capillary apparatus under controlled heating rate. |
| Acid Value | Acid-Base Titration | Neutralization of carboxylic acid groups with standardized NaOH solution using phenolphthalein or potentiometric endpoint detection. |
| Organic Volatile Impurities | GC-FID | Separation and quantification of residual solvents (e.g., toluene, xylene, DMF) by gas chromatography with flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion via laser scattering pattern to determine D10, D50, D90 values. |
| Bulk Density | Graduated Cylinder Method | Mass of material freely poured into a calibrated cylinder divided by its settled volume. |
| Sulfated Ash | Gravimetric Analysis | Incineration of sample with sulfuric acid followed by high-temperature ashing and gravimetric determination of sulfate-resistant residue. |
