Manufacturing Quality Control of 2,4-Difluorobenzonitrile
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Purity | Gas Chromatography (GC) | Using a capillary column for separation and FID detector for quantitative analysis of main component content, to evaluate sample purity. Suitable for volatile organic compounds. |
| Impurity Content | Gas Chromatography-Mass Spectrometry (GC-MS) | Combining GC separation with MS identification capability to identify and quantify trace impurities (such as isomers, by-products, residual solvents, etc.). |
| Moisture | Karl Fischer Titration | Determining trace moisture in the sample using coulometric or volumetric methods, ensuring product dryness meets storage and reaction requirements. |
| Appearance and Color | Visual Color Comparison / Spectrophotometry | Assessing clarity and color by standard color charts or measuring absorbance at specific wavelengths using UV-Vis spectrophotometer. |
| Melting Point | Capillary Melting Point Method | Determining the temperature at which a substance transitions from solid to liquid, used to preliminarily assess purity and consistency of the substance. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Releasing volatile solvents by heating the sample, then analyzing them by GC-FID or GC-MS to quantify common organic solvent residues (such as toluene, DMF, etc.). |
| Heavy Metals | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Highly sensitive detection of trace metal elements (such as Pb, As, Cd, Hg) to ensure compliance with pharmacopoeia or industrial safety standards. |
| pH Value (in aqueous solution) | pH Meter Measurement | Measuring the pH of the sample after preparing it into an aqueous solution to assess its acidity or alkalinity, indirectly reflecting the presence of acidic or basic impurities. |
| Content Determination (Main Component) | High Performance Liquid Chromatography (HPLC-UV) | Using reversed-phase chromatography columns and UV detectors (e.g., 254 nm) to quantitatively determine the main component content, suitable for thermally unstable or polar compounds. |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Confirming molecular structure using ¹H NMR, ¹³C NMR, or 19F NMR to verify the identity of the target compound and the correct position of substituents. |
