Manufacturing Quality Control of 1-Bromo-2,3-difluorobenzene
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, state, and visible impurities under natural light or a standard light source. |
| Purity | Gas Chromatography (GC) | Use capillary column gas chromatography to identify components by retention time and quantify them using peak area normalization to determine the main component content and organic impurities. |
| Moisture | Karl Fischer Method | Determine water content in the sample through coulometric or volumetric titration based on the quantitative reaction between iodine and sulfur dioxide in the presence of pyridine/imidazole. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Place the sample in a sealed headspace vial, heat it to equilibrium, take the gas phase for injection, and use GC to separate and quantify residual organic solvents (e.g., toluene, dichloromethane). |
| Inorganic Impurities (Ash Content) | Ignition Residue Method | Heat the sample at high temperature until constant weight, weigh the mass of the remaining inorganic material, and calculate the ash content. |
| Bromine Content | Potentiometric Titration or Ion Chromatography | Potentiometric Titration: Use silver nitrate as the titrant with a silver indicator electrode to determine bromide ion content; Ion Chromatography: Separate using an anion exchange column and quantify via conductivity detection. |
| pH Value (if applicable) | pH Meter Method | Prepare the sample as an appropriately concentrated aqueous solution or suspension and measure its acidity or alkalinity using a calibrated pH meter (applicable to dispersible systems). |
| Density | Densitometer Method or Pycnometer Method | Measure the density of liquid samples at a specified temperature using a digital densitometer or a standard pycnometer. |
| Refractive Index | Abbe Refractometer Method | Under constant temperature conditions, use an Abbe refractometer to measure the refractive index of the sample for sodium light (589.3 nm), used for auxiliary identification and purity determination. |
