Manufacturing Quality Control of 7-Hydroxyquinoline
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 240-260 nm. |
| Related Substances | HPLC-UV | Separation and detection of impurities (e.g., quinoline, 7-chloroquinoline, oxidation by-products) using gradient HPLC with UV monitoring. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via iodine-sulfur dioxide reaction in a methanol-based solvent system. |
| Residue on Ignition | Gravimetric Analysis | Determination of inorganic ash content after high-temperature incineration (700-800 C) followed by weighing of residual residue. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of heavy metals (Pb, Cd, Hg, As) after acid digestion, using plasma emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions following sample dissolution and filtration. |
| Sulfated Ash | Gravimetric Analysis | Weight measurement of residue after sulfuric acid treatment and subsequent ignition to constant weight. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using calibrated capillary tube method per USP/Ph. Eur. guidelines. |
| Organic Volatile Impurities | GC-FID | Detection and quantification of residual solvents (e.g., methanol, acetone, toluene) using gas chromatography with flame ionization detection. |
| Appearance | Visual Inspection | Assessment of physical state and color against defined standards (white to off-white crystalline powder). |
| Solubility in Ethanol | Qualitative Test | Evaluation of complete dissolution in specified volume of ethanol under standardized conditions (e.g., 1 g in 50 mL, 20 C). |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
