Manufacturing Quality Control of 4-BROMO-1(2H)-ISOQUINOLONE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a 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; reported as area percent relative to total chromatogram. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents based on retention time and peak area calibration. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element detection of trace metals after acid digestion, based on mass-to-charge ratio and isotopic abundance. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with suppressed conductivity detection; quantified against chloride standard. |
| Residue on Ignition | Gravimetric Analysis | Mass measurement of inorganic residue remaining after high-temperature ashing at 700-800 C. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid, observed visually in a calibrated capillary tube. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of sample under controlled white light against defined standards. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity versus angle to calculate volume-based particle size distribution. |
| Bulk Density | Tap Density Tester | Measurement of mass per unit volume after standardized mechanical tapping of a powder sample in a graduated cylinder. |
| Microbial Limits | Membrane Filtration | Quantitative recovery and enumeration of aerobic microorganisms from solution using sterile membrane filtration and agar culture. |
