Manufacturing Quality Control of 1,4-Dibromobenzene
| Test Item | Common Test Methods | Method Overview |
|---|---|---|
| Appearance and Physical State | Visual Inspection | Observe the color, state, and presence of impurities. Pure product appears as white or off-white crystalline powder, free of visible foreign matter. |
| Melting Point | Melting Point Determination (Capillary Method) | Determine the melting temperature using a melting point apparatus. The standard melting point of 1,4-dibromobenzene is approximately 86–88°C, used to assess purity. |
| Assay | Gas Chromatography (GC) | Use a gas chromatograph equipped with an FID detector. Qualitative analysis is based on retention time, while quantitative analysis of the main component is performed using peak area normalization or external standard method. |
| Impurity Analysis | High-Performance Liquid Chromatography (HPLC) | Suitable for detecting non-volatile or thermally unstable impurities; capable of separating and quantifying trace organic impurities such as isomers or by-products. |
| Bromine Content | Elemental Analysis (Combustion-Ion Chromatography/Titration) | After combusting the sample at high temperature, determine the released bromide ion content to verify whether the bromine content in the molecule matches the theoretical value. |
| Moisture Content | Karl Fischer Titration | Use KF reagent to accurately measure the moisture content in the sample, suitable for quality control with strict moisture sensitivity requirements. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detect possible residual organic solvents (e.g., benzene, toluene, ethanol) from the manufacturing process, ensuring compliance with ICH limit standards. |
| Crystal Form Analysis | X-ray Diffraction (XRD) | Analyze the crystal structure of the solid sample to confirm the presence of polymorphism and ensure batch-to-batch consistency. |
| Infrared Characteristic Functional Groups | Fourier Transform Infrared Spectroscopy (FTIR) | Compare the infrared absorption spectrum with the standard spectrum to confirm the presence of characteristic functional groups such as C-Br and aromatic rings in the molecular structure. |
