Manufacturing Quality Control of 4-Bromo-3-fluorobenzonitrile
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 220-254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3A/B. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., acetone, methanol, toluene) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent; water reacts stoichiometrically with iodine and sulfur dioxide in pyridine/methanol medium. |
| Heavy Metals | ICP-MS | Multi-element quantification of Pb, Cd, Hg, As, and others after acid digestion, using isotopic detection for high sensitivity and low detection limits. |
| Chloride Impurity | Ion Chromatography | Separation of chloride anion on an anion-exchange column with suppressed conductivity detection; quantified against NaCl calibration curve. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after incineration at 600-700 C, followed by precise weighing of the cooled crucible. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature range using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of neat solid sample under controlled white light against standard references. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser scattering principles to derive D10, D50, D90 values per ISO 13320. |
| Bulk Density | ASTM D1895 Method A | Measurement of mass per unit volume for freely settled powder in a standardized cylinder using calibrated volumetric measure. |
| Organic Volatile Impurities (OVI) | GC-MS | Targeted and untargeted screening of volatile organic impurities using headspace GC coupled to mass spectrometry for identification and quantification. |
