Manufacturing Quality Control of 4-Bromo-2-iodobenzoic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specific wavelength using reverse-phase C18 column and calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., bromo/iodo isomers, debromo/deiodo analogs) via retention time comparison and peak area normalization. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., DMF, ethyl acetate) using flame ionization detection with polar capillary column. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration based on iodine consumption in pyridine-methanol buffer. |
| Heavy Metals | ICP-OES | Quantifies elemental impurities (Pb, Cd, Hg, As, etc.) after acid digestion by measuring atomic emission intensities at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled combustion in sulfuric acid medium and high-temperature ashing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and presence of impurities. |
| Optical Rotation | Polarimetry | Measures specific rotation using sodium D-line light to detect chiral impurities or enantiomeric excess (if applicable). |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles in suspension by measuring angular variation of scattered laser light. |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume after standardized mechanical tapping of a known powder mass in a graduated cylinder. |
| pH of Aqueous Slurry | Potentiometric pH Measurement | Measures hydrogen ion activity in a saturated aqueous slurry using calibrated glass electrode and reference electrode. |
