Manufacturing Quality Control of 4-Bromobenzonitrile
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, physical state, and presence of visible impurities. Typically appears as white to off-white crystalline powder. |
| Assay (Purity) | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column and UV detector (e.g., 220 nm), with methanol-water or acetonitrile-water as mobile phase. The assay is calculated using external standard or area normalization method. |
| Melting Point | Melting Point Determination (Capillary Method) | Determine the melting temperature range using a melting point apparatus. Compare with reference value (literature value approximately 97–100°C) to assess purity. |
| Residual Solvents | Gas Chromatography (GC) | Detect solvents possibly remaining from manufacturing (e.g., methanol, ethanol, acetonitrile) using headspace GC. Results must comply with ICH Q3C limits. |
| Moisture Content | Karl Fischer Titration | Measures water content in the sample using coulometric or volumetric methods; suitable for trace moisture analysis. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Similar to assay determination; uses gradient elution to separate impurity peaks, detects and quantifies related substances to evaluate impurity profile. |
| Bromine Content | Ion Chromatography or Elemental Analysis | Determines bromine content in the organic compound to verify the presence and stoichiometric ratio of bromine in the molecular structure; commonly used for raw material verification. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Sample is digested and then analyzed for residual heavy metals such as lead, arsenic, cadmium, and mercury. Must meet pharmacopoeial or safety standards (e.g., Chinese Pharmacopoeia, USP). |
| Particle Size Distribution | Laser Particle Size Analysis | Used to control physical properties of raw materials prior to formulation, particularly important for dissolution and uniformity in solid dosage forms. |
| Infrared Spectrum (IR) | Fourier Transform Infrared Spectroscopy (FT-IR) | Obtain IR spectrum by pressing sample with KBr or using ATR method. Compare with reference spectrum to confirm consistency of chemical structure. |
