Manufacturing Quality Control of 2,5-Dichlorobenzonitrile
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 2,5-dichlorobenzonitrile peak area relative to a calibration curve using an internal or external standard. |
| Related Substances | Gas Chromatography (GC) with FID or MS detection | Separates and quantifies impurities (e.g., isomers, chlorinated by-products) based on retention time and response factors. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects and quantifies volatile organic solvents (e.g., dichloromethane, toluene) via equilibrium vapor phase analysis. |
| Moisture Content | Karl Fischer Titration | Measures water content by electrochemical titration where iodine reacts stoichiometrically with water in a pyridine-methanol solvent system. |
| Chloride Ion Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using an anion-exchange column and conductivity detection. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies trace metals (e.g., Pb, Cd, Hg, As) by atomization and excitation in high-temperature plasma, followed by elemental emission measurement. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid transitions to liquid, indicating purity and identity via crystalline lattice integrity. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles or discoloration under controlled lighting and against standard references. |
| Acid-Base Impurities | Acid-Base Potentiometric Titration | Determines acidic or basic impurities by titration with standardized NaOH or HCl and monitoring pH inflection point. |
| Sulfated Ash | Gravimetric Analysis (Weight Loss on Ignition) | Measures inorganic residue after combustion at 700-800 C following sulfuric acid treatment; indicates non-volatile inorganic contaminants. |
| Particle Size Distribution | Laser Diffraction Particle Size Analysis | Measures size distribution of solid particles in suspension by analyzing angular variation of scattered laser light intensity. |
| Bulk Density | ASTM D1895 Method A (Tapped Density) | Determines mass per unit volume of powder after controlled tapping; reflects flowability and packing behavior for handling and formulation. |
