Manufacturing Quality Control of 2-BROMO-4-CHLOROBENZONITRILE
| 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 | Gas Chromatography (GC) with Headspace sampling | Volatile organic impurities are vaporized in sealed vials and quantified by GC-FID or GC-MS relative to internal standards. |
| Water Content | Karl Fischer Titration (Coulometric mode) | 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) | Sample digested in acid matrix, then elemental emission intensities measured at characteristic wavelengths for quantitative metal analysis. |
| Chloride Impurities | Ion Chromatography (IC) with conductivity detection | Separation of anions on an ion-exchange column followed by suppressed conductivity detection for quantitative chloride determination. |
| 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 standard calibration. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range over which solid transforms to liquid under controlled heating rate. |
| Appearance | Visual Inspection in Standard Light | Assessment of physical state, color, and clarity of sample against white/black background under controlled daylight-equivalent illumination. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Sample heated at 700-800 C in platinum crucible; residue weight measured after cooling in desiccator to determine inorganic ash content. |
| pH of Aqueous Suspension | pH Meter Measurement | Aqueous slurry prepared per USP general chapter <791>; pH measured with calibrated electrode after equilibration. |
| Particle Size Distribution | Laser Diffraction Particle Size Analyzer | Analysis of light scattering pattern from dispersed particles to calculate volume-based size distribution using Mie theory. |
| Organic Volatile Impurities (Total) | Gas Chromatography (GC) with Flame Ionization Detection (FID) | Sum of specified residual solvents determined individually by GC-FID and reported as total volatile organics per ICH Q3C guidelines. |
