Manufacturing Quality Control of 5-Ethylpyridine-2,3-dicarboxylic acid diethyl ester
| Test Item | Common Test Method | Method Summary |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, state, and presence of impurities under natural or standard lighting; it should be a colorless to pale yellow transparent liquid. |
| Identification | Infrared Spectroscopy (IR) Proton Nuclear Magnetic Resonance (¹H NMR) |
Confirm structural consistency by comparing characteristic IR absorption peaks (e.g., C=O, C–N, aromatic rings) or ¹H NMR chemical shifts with reference spectra. |
| Assay | 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 220 nm or 254 nm). Calculate the main component content using external standard or area normalization method, typically requiring ≥98.0%. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Using the same or optimized conditions as in the assay, separate and quantify potential impurities (e.g., starting materials, intermediates, degradation products). Individual impurity is typically ≤0.5%, total impurities ≤1.0%. |
| Water Content | Karl Fischer Titration | Quantitatively determine water content based on the reaction between KF reagent and water in the sample via potentiometric titration. Typically requires ≤0.5%. |
| Residual Solvents | Gas Chromatography (GC) | Using headspace or direct injection with an FID detector, detect residual organic solvents (e.g., ethanol, dichloromethane, toluene) possibly remaining from synthesis according to ICH Q3C guidelines, ensuring compliance with permitted limits. |
| Melting Point / Boiling Point | Melting Point Apparatus or Boiling Point Apparatus | For solids or high-purity liquids, measure melting or boiling point range and compare with literature values to assist in purity assessment. (Note: Diethyl 5-ethylpyridine-2,3-dicarboxylate is a liquid at room temperature; boiling point or refractive index is usually measured.) |
| Refractive Index (Optional) | Refractometry | Measure the refractive index at a specified temperature (e.g., 20°C) as a physical constant for auxiliary identification and purity evaluation. |
