Manufacturing Quality Control of 4-Bromo-2-fluorobiphenyl
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, physical state, and presence of visible impurities in the sample under natural light or standard illumination. |
| Purity | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with methanol/water or acetonitrile/water as the mobile phase. Detect using a UV detector and quantify the main component via external standard method or area normalization method. |
| Assay | HPLC or Gas Chromatography (GC) | HPLC is suitable for non-volatile or thermally unstable samples; GC is used for volatile samples, provided thermal stability is confirmed. Quantification is performed using a calibration curve method. |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Use ¹H-NMR and ¹³C-NMR to confirm the compound's structure by verifying that the chemical environments of hydrogen and carbon atoms match the target structure. |
| Halogen Element Analysis | Elemental Analysis (EA) or X-ray Fluorescence Spectroscopy (XRF) | EA precisely measures the content of elements such as C, H, Br, and F; XRF provides rapid, non-destructive detection of bromine and fluorine elements and their relative concentrations. |
| Residual Solvents | Gas Chromatography (GC) | According to the Chinese Pharmacopoeia or ICH guidelines, use headspace-GC to detect organic solvents (e.g., toluene, dichloromethane) that may remain from the manufacturing process. |
| Moisture Content | Karl Fischer Titration | Determine moisture content using coulometric or volumetric methods, suitable for trace moisture analysis. |
| Melting Point | Melting Point Apparatus | Determine the initial and final melting temperatures using an automatic melting point instrument or capillary method to assess purity and consistency. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Detect residual heavy metals such as lead, cadmium, mercury, and arsenic to ensure compliance with impurity limits for pharmaceuticals or fine chemicals. |
| Individual Impurity and Total Impurities | HPLC Method | Analyze impurity peaks in the HPLC chromatogram to calculate the levels of individual and total impurities, typically using the self-reference method or impurity reference standard method. |
