Manufacturing Quality Control of 2,3-DICHLORO-5-NITROPYRIDINE
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and physical state (e.g., whether it is a pale yellow to brown crystalline powder) and check for foreign matter with the naked eye. |
| Melting Point | Melting Point Determination (Capillary Method or Digital Melting Point Apparatus) | Determine the melting temperature range of the sample under standard conditions to assess purity and consistency; typically reference literature values of approximately 140–143 °C. |
| Content (Main Component Purity) | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a UV detector (e.g., at 254 nm) and external standard or area normalization method to determine the content of the main component. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separate and quantify potential process-related or degradation impurities—such as unreacted starting materials or by-products—under the same conditions as content determination. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Constant Weight Drying Method | Dry the sample at a specified temperature (e.g., 105 °C) until constant weight is achieved, then calculate the percentage of mass loss to evaluate water and volatile impurity content. |
| Residue on Ignition (Ash) | High-Temperature Incineration Method | Incinerate the sample at high temperature (e.g., 600–800 °C) and weigh the residual inorganic material to assess the level of inorganic impurities. |
| Water Content | Karl Fischer Titration | Use Karl Fischer titration to accurately determine trace water content in the sample, suitable for organic compounds sensitive to moisture. |
| Fourier Transform Infrared Spectroscopy (FT-IR) Identification | Fourier Transform Infrared Spectroscopy (FT-IR) | Obtain the sample’s infrared absorption spectrum and compare it with a reference spectrum to confirm characteristic functional groups (e.g., nitro group, C–Cl bond). |
| Proton Nuclear Magnetic Resonance Spectroscopy (¹H NMR) | Nuclear Magnetic Resonance Spectroscopy | Measure the ¹H NMR spectrum in a deuterated solvent (e.g., CDCl₃) to verify structural features and assess purity, aiding in impurity identification. |
