Manufacturing Quality Control of ISOPHTHALAMIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 230 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., acetone, methanol, toluene) per ICH Q3C guidelines. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and Cr after acid digestion, using plasma optical emission spectroscopy. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential inflection. |
| Sulfated Ash | Gravimetric Method | Ignition of sample at 700-750 C after sulfuric acid treatment; residue weighed as inorganic sulfate ash. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine reagent; water reacts stoichiometrically with iodine and sulfur dioxide in pyridine/methanol medium. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range at which solid transforms to liquid. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light and specified viewing conditions. |
| Particle Size Distribution | Laser Diffraction | Measurement of scattered laser light intensity as a function of angle to calculate volume-based particle size distribution. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode after equilibration. |
| Organic Volatile Impurities (OVI) | GC-MS | Targeted and non-targeted screening of volatile organic impurities using gas chromatography coupled with mass spectrometry detection. |
