Manufacturing Quality Control of 3-Bromo-4-methylbenzonitrile
| 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 under optimized chromatographic conditions. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of impurities using reversed-phase C18 column and gradient elution with UV absorbance detection. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) with FID | Volatile solvent residues are vaporized in sealed vials, injected into GC, and quantified by external calibration. |
| Moisture Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Sample digested in acid matrix; elemental emission intensities measured at characteristic wavelengths for semi-quantitative screening. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation of anions on ion-exchange column followed by quantitative detection via electrical conductivity of eluent stream. |
| Sulfated Ash | Gravimetric Analysis (Ignition at 700 C) | Sample incinerated to oxidize organic matter; residual inorganic ash is weighed after cooling in desiccator. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually as solid-to-liquid phase change under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of visible particulates or foreign matter under standardized lighting and viewing conditions. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution of the compound in specified solvent and concentration. |
| pH of Aqueous Suspension | pH Meter Measurement | Electrode-based potentiometric measurement of hydrogen ion activity in a saturated aqueous suspension of the compound. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to calculate volume-based particle size distribution in dispersed sample. |
