Manufacturing Quality Control of 4,4'-Dibromobenzophenone
| Test Item | Common Testing Method | Method Summary |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, state, and presence of visible impurities under natural light or a standard light source. It should typically be a white to off-white crystalline powder. |
| Purity/Content | 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 (e.g., at 254 nm) and calculate the main component content via external standard method or area normalization to assess purity. |
| Melting Point | Capsule Melting Point Determination | Load the sample into a melting point capillary tube and heat it at a specified rate in a melting point apparatus. Record the initial and final melting temperatures and compare them with the standard values (approximately 86–89 °C) to judge purity and consistency. |
| Moisture | Karl Fischer Titration | Determine the water content by reacting iodine and sulfur dioxide in the presence of pyridine/imidazole using coulometric or volumetric methods to control product dryness. |
| Residual Solvents | Gas Chromatography (GC) | Use headspace or direct injection with polar or non-polar capillary columns for separation. Detect common organic solvents (e.g., toluene, acetone, dichloromethane) using an FID detector and ensure compliance with ICH Q3C limit requirements. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Digest the sample with acid and measure the contents of heavy metals such as lead, cadmium, mercury, and arsenic using AAS or ICP-MS to meet pharmacopoeia or industry limits (typically ≤10 ppm). |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separate and detect possible process impurities or degradation products (e.g., monobromo derivatives, oxidation products) using a gradient elution program. Calculate the content of each impurity based on peak areas to meet quality standards (e.g., individual impurity ≤0.5%, total impurities ≤1.0%). |
| Infrared Spectral Identification | Fourier Transform Infrared Spectroscopy (FT-IR) | Prepare KBr pellets or use ATR mode to collect the infrared spectrum of the sample. Compare characteristic absorption peaks (e.g., carbonyl ~1660 cm⁻¹, aromatic rings ~1600, 1500 cm⁻¹, C–Br ~600–700 cm⁻¹) with standard spectra for structural confirmation. |
