Manufacturing Quality Control of 5,7-DIBROMO-8-HYDROXYQUINOLINE
| 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 to 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 spiked samples. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify common organic solvents (e.g., methanol, acetone, DMF) against calibration curves. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element analysis after acid digestion; quantifies total heavy metals by atomic emission spectroscopy using lead as the indicator element. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with suppressed conductivity detection. |
| Moisture Content | Karl Fischer Titration | Volumetric titration using iodine-based reagent to determine water content via stoichiometric reaction with pyridine and methanol. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using calibrated capillary tube method per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light against established reference standards. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after high-temperature ashing (700–800 C) and weighing. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode following standard buffer calibration. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser scattering to determine D10, D50, D90 values per ISO 13320. |
| Organic Volatile Impurities (OVI) | GC-MS | Screening and semi-quantitative identification of unknown volatile organics using mass spectral library matching and retention index comparison. |
