| Organic Synthesis | Synthesis of coordination compounds | Metal coordination |
Manufacturing Quality Control of 5-Chloro-8-hydroxyquinoline
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state, and presence of visible impurities under natural or standard lighting conditions. |
| Melting Point | Capillary Melting Point Method | Place the sample in a capillary tube and gradually heat it using a melting point apparatus; record the initial and final melting temperatures to assess purity and substance consistency. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase column (e.g., C18) with a UV detector (typically at 254 nm or 280 nm); quantify the active ingredient using external or internal standard methods. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separate the main peak from impurity peaks using gradient or isocratic elution; detect and quantify organic impurities such as residual solvents, synthesis intermediates, or degradation products. |
| Solubility | Solubility Test | Add the sample to solvents of different polarities (e.g., water, ethanol, methanol, chloroform), shake, and observe dissolution to evaluate solubility characteristics. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying Method | Dry the sample at a specified temperature (e.g., 105°C) to constant weight; calculate the percentage weight loss to estimate moisture and volatile content. |
| Sulfated Ash | Sulfated Residue Method | Treat the sample with sulfuric acid, then incinerate at high temperature; weigh the residue to determine inorganic impurity content. |
| Chlorine Content | Elemental Analysis or Ion Chromatography | Determine organic chlorine content via combustion-absorption titration or ion chromatography to confirm the presence and proportion of chlorine in the molecule. |
| Moisture Content | Karl Fischer Titration | Use electrochemical titration to measure trace amounts of water in the sample; suitable for solid samples with low moisture levels. |
| Structural Confirmation | Infrared Spectroscopy (IR), Nuclear Magnetic Resonance (NMR), Mass Spectrometry (MS) | Use IR to identify functional groups (e.g., OH, aromatic rings); ¹H-NMR, ¹³C-NMR, and MS provide molecular structure information for raw material identification. |
