Manufacturing Quality Control of 4-Bromo-3-fluorobenzaldehyde
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities by retention time comparison and relative response factors against reference standards. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents using capillary GC with flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures trace water via coulometric or volumetric titration based on iodine-sulfur dioxide redox reaction. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Hg, As) by plasma ionization and mass spectrometric detection. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after anion exchange separation. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid phase transition using controlled heating and optical observation. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against standard reference under controlled lighting and viewing conditions. |
| Acidity (as HBr) | Acid-Base Titration | Titrates acidic impurities with standardized NaOH solution using phenolphthalein indicator. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to detect chiral impurities or enantiomeric excess (if applicable). |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles in suspension using angular scattering pattern of laser beam. |
