Manufacturing Quality Control of 5,7-Diiodo-8-quinolinol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; identification based on retention time relative to reference standards. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, acetone, DMF) based on calibrated response factors. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element determination of toxic metals (Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma optical emission spectrometry. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with conductivity detection, referenced to sodium chloride standard. |
| Moisture Content | Karl Fischer Titration | Volumetric titration with iodine-based reagent where water reacts stoichiometrically to determine total water content. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement using capillary tube method per USP <741>, recording onset and clear point under controlled heating rate. |
| Loss on Drying | Gravimetric (Thermogravimetric) | Weight loss measured after drying sample at 105 C for 2 hours; reflects volatile matter including residual solvents and water. |
| Residue on Ignition | Sulfated Ash Gravimetry | Mass of inorganic residue remaining after high-temperature ashing (600–700 C) followed by sulfuric acid treatment and ignition. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser scattering to determine D10, D50, and D90 values per ISO 13320. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | pH measured in a 1% w/v suspension in purified water using calibrated pH electrode per USP <791>. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light at 20 C using sodium D-line (589 nm); confirms chiral integrity if applicable (though compound is achiral, used for batch consistency). |
