Manufacturing Quality Control of 3-IODOPHTHALIC ANHYDRIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using HPLC coupled with diode array detection; impurities quantified relative to main peak using response factors. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify common organic solvents based on retention time and peak area calibration. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent where water reacts stoichiometrically to determine trace moisture content. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion using inductively coupled plasma optical emission spectrometry with detection at characteristic emission wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with suppressed conductivity detection; chloride quantified using external calibration. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range at which solid-to-liquid phase change occurs. |
| Loss on Drying | Gravimetric Analysis | Mass loss measured after drying under controlled temperature and vacuum conditions, expressed as weight percent. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against established reference standards under controlled lighting conditions. |
| Residue on Ignition | Sulfated Ash Test | Inorganic residue determined gravimetrically after high-temperature incineration following sulfuric acid treatment. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to calculate size distribution based on Mie theory for dry or dispersed samples. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, used to assess chiral purity and identity. |
