Manufacturing Quality Control of 4-BROMO-3,5-DIMETHYL-BENZONITRILE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 220-254 nm, comparing peak area to calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., isomers, bromination by-products) via gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents (e.g., toluene, acetonitrile) using capillary GC with flame ionization detection. |
| Moisture Content | Karl Fischer Titration | Determines water content by coulometric or volumetric titration using iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-OES | Measures trace metal contaminants (e.g., Pb, Cd, Ni) after acid digestion by optical emission spectroscopy of excited atoms/ions. |
| Chloride Impurity | Ion Chromatography | Quantifies chloride ions using suppressed conductivity detection after separation on anion-exchange column. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity via thermal behavior. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled lighting against standard white background. |
| Bulk Density | ASTM D1895 | Measures mass per unit volume of freely settled powder using standardized graduated cylinder and balance. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of dry powder by measuring angular variation in intensity of laser light scattered by particles. |
| Loss on Drying | Gravimetric Heating | Determines volatile content by measuring weight loss after heating sample at specified temperature (e.g., 105 C) for fixed time. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in saturated aqueous suspension using calibrated glass electrode pH meter. |
