Manufacturing Quality Control of 4,7-Dichloroquinoline
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, condition, and presence of visible impurities in the sample. Usually appears as a white to light yellow crystalline powder. |
| Purity/Content Determination | High-Performance Liquid Chromatography (HPLC) | Using a reverse-phase C18 chromatographic column with methanol-water or acetonitrile-water as the mobile phase, and UV detector (e.g., 254 nm) for detection. The main component content is calculated using external or internal standard methods. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Gradient elution under the same HPLC conditions is used to detect and quantify each impurity peak, assessing total impurity levels and individual impurity limits. |
| Melting Point | Melting Point Apparatus Method | Determine the initial and final melting temperatures using an automatic or manual melting point apparatus, and compare with the standard value (literature value approximately 90–93°C). |
| Moisture | Karl Fischer Titration | Determine moisture content using coulometric or volumetric Karl Fischer titration. Suitable for low moisture detection (usually controlled at ≤0.5%). |
| Residual Solvents | Gas Chromatography (GC) | Use a capillary column (e.g., DB-624), nitrogen as the carrier gas, and FID detector to detect possible residual organic solvents (such as methanol, ethanol, dichloromethane, etc.). |
| Heavy Metals | Atomic Absorption Spectrometry (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Determine the content of heavy metals such as lead, cadmium, mercury, and arsenic after sample digestion, complying with pharmacopoeia or customer limit requirements. |
| Sulfate Ash/Residue on Ignition | Residue on Ignition Method | Ignite the sample at high temperature (approximately 600–800°C) until constant weight, weigh the residue, and calculate the percentage of sulfate ash. |
| Structural Confirmation | Nuclear Magnetic Resonance (NMR), Mass Spectrometry (MS), Infrared Spectroscopy (IR) | Used for raw material confirmation: ¹H-NMR and ¹³C-NMR verify hydrogen and carbon structure; MS determines molecular ion peak; IR identifies characteristic functional groups. |
