Manufacturing Quality Control of 8-Hydroxyquinoline-N-oxide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 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 relative to reference standards or threshold limits. |
| Loss on Drying | Gravimetric Method | Measurement of mass loss after drying at 105 C for 2 hours under controlled atmospheric conditions. |
| Residue on Ignition | Sulfated Ash Method | Determination of inorganic residue after charring and ignition at 700-750 C, followed by weighing of the sulfate ash. |
| Heavy Metals (as Pb) | AAS or ICP-OES | Quantification of total heavy metals by atomic absorption spectroscopy or inductively coupled plasma optical emission spectrometry after acid digestion. |
| Chloride | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| Sulfate | Turbidimetric Method | Reaction with barium chloride under acidic conditions to form BaSO4 precipitate; quantified by measuring turbidity at 420 nm. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent; water reacts stoichiometrically to determine trace moisture content. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated capillary apparatus per USP/Ph. Eur. guidelines. |
| pH of Aqueous Solution | pH Meter | Measurement of hydrogen ion activity in a 1% w/v aqueous suspension using a calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to calculate particle size distribution in a dispersed sample. |
| Organic Volatile Impurities | GC-FID | Detection and quantification of residual solvents using gas chromatography with flame ionization detection and internal standard calibration. |
