Manufacturing Quality Control of 5-Bromoisatin
| 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 254 nm. |
| Related Substances | HPLC-DAD | Separation and identification of impurities by retention time and UV spectral matching; quantified relative to main peak using external standard or area normalization. |
| Residual Solvents | GC-FID | Volatile organic solvents extracted and quantified by gas chromatography with flame ionization detection using calibrated standards. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via iodine-sulfur dioxide reaction in pyridine/methanol medium. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of heavy metals after acid digestion, based on element-specific atomic emission intensities. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride anions using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Residue mass measured after high-temperature incineration of sample in sulfuric acid medium, indicating inorganic impurities. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change using calibrated capillary method per USP <741>. |
| Organic Volatile Impurities | GC-MS | Identification and quantification of trace volatile organics using gas chromatography coupled with mass spectrometric detection. |
| Particle Size Distribution | Laser Diffraction | Size distribution determined from angular scattering pattern of laser beam passed through dispersed sample suspension. |
| Bulk Density | ASTM D1895 | Mass per unit volume measured for freely settled powder in a standardized cylinder under controlled conditions. |
| Residual Palladium (if catalytically hydrogenated) | ICP-MS | Ultra-trace quantification of palladium after microwave-assisted digestion using isotope-dilution mass spectrometry. |
