Manufacturing Quality Control of 5-Bromo-1,3-benzenedicarbonitrile
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 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 relative response factors. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., DMF, acetone, methanol) based on calibrated external 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 toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using isotopic detection and internal standard correction. |
| Chloride Impurity | Ion Chromatography | Separation of chloride anions on anion-exchange column with suppressed conductivity detection; quantified via calibration curve. |
| Sulfate Impurity | Ion Chromatography | Anion-exchange separation followed by suppressed conductivity detection; sulfate quantified using external calibration standards. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature at which solid-to-liquid phase change occurs under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under standardized white light and against specified reference standards. |
| Particle Size Distribution | Laser Diffraction | Measurement of scattered laser light intensity at multiple angles to calculate particle size distribution based on Mie scattering theory. |
| Bulk Density | ASTM D1895 Method A | Determination of mass per unit volume for freely settled powder using a calibrated graduated cylinder and analytical balance. |
| Loss on Drying | Gravimetric Analysis | Weight loss measured after drying sample at specified temperature (e.g., 105 C) under vacuum or nitrogen until constant mass is achieved. |
