Manufacturing Quality Control of 4-Bromo-2-fluorobenzonitrile
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile organic impurities are equilibrated in headspace vial and quantified by GC-FID or GC-MS against calibrated standards. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Elemental quantification after acid digestion by measuring characteristic atomic emission wavelengths in plasma-excited sample aerosol. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation of anions on ion-exchange column followed by quantitative detection via suppressed conductivity measurement. |
| Residual Palladium | ICP-OES | Quantification of palladium catalyst residue after microwave-assisted acid digestion using element-specific emission lines. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation on reversed-phase C18 column; impurities detected at 220 nm and quantified relative to main peak using external standardization. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or optically as solid-to-liquid phase change under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against standard white background under controlled lighting conditions. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein indicator; calculated as mg KOH/g sample. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity pattern to determine volume-based particle size distribution in dispersed dry or wet sample. |
| Bulk Density | ASTM D1895 Method A (Tapped Density) | Mass per unit volume measured after mechanical tapping of a graduated cylinder containing the free-flowing powder. |
