Manufacturing Quality Control of 4-CHLOROBENZYLIDENE PHTHALIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by retention time and UV peak area against reference standard calibration curve. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., acetone, methanol) based on flame ionization response after headspace injection. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration with iodine generated in situ via electrochemical reaction. |
| Heavy Metals | ICP-OES | Quantifies metals (Pb, Cd, Hg, As, Cr) after acid digestion by atomic emission intensity at element-specific wavelengths. |
| Chloride Content | Potentiometric Titration | Measures chloride ions using silver nitrate titrant and silver/silver chloride indicator electrode potential change. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary tube under controlled heating rate. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under standardized white light and viewing conditions. |
| Loss on Drying | Gravimetric Method | Measures mass loss after drying under specified temperature and vacuum/time conditions to determine volatile content. |
| Residue on Ignition | Sulfated Ash Test | Quantifies non-volatile inorganic residue after high-temperature combustion in presence of sulfuric acid. |
| Specific Optical Rotation | Polarimetry | Measures rotation angle of plane-polarized light induced by chiral centers in solution at specified concentration and path length. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular scattering pattern of laser beam passing through dispersed sample. |
