Manufacturing Quality Control of 3-CHLOROPHTHALIC ANHYDRIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with UV detection | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography. |
| Moisture Content | Karl Fischer titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based reagent. |
| Melting Point | Capillary melting point apparatus | Thermal transition measurement by observing the temperature range at which solid transforms to liquid under controlled heating. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element detection via plasma ionization followed by mass spectrometric quantification at trace levels. |
| Residue on Ignition | Gravimetric analysis | Mass difference measured before and after high-temperature ashing to determine non-volatile inorganic impurities. |
| Acid Value | Acid-base titration with NaOH | Neutralization of acidic functional groups using standardized sodium hydroxide solution with phenolphthalein indicator. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separation and quantification of residual solvents or low-boiling impurities using flame ionization detection. |
| Color (APHA) | Visual comparison or spectrophotometric measurement | Comparison of sample solution color intensity against APHA platinum-cobalt standards at 430 nm. |
| Particle Size Distribution | Laser diffraction | Analysis of scattered light patterns from dispersed particles to calculate size distribution based on Mie theory. |
| Sulfated Ash | Gravimetric analysis | Mass of inorganic residue after ignition with sulfuric acid pretreatment to convert metals to sulfates. |
| Related Substances | HPLC with diode array detection | Identification and quantification of structurally similar impurities using retention time and spectral matching against reference compounds. |
