Manufacturing Quality Control of Pramipexole impurity 7
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state, and presence of visible foreign particles under natural light or standard illumination. |
| Melting Point | Capillary Melting Point Determination | Determine the temperature range at which a compound transitions from solid to liquid using a melting point apparatus, used to assess purity and consistency of the compound. |
| Specific Rotation | Polarimetry | Measure the optical rotation of a sample solution at a specific wavelength (e.g., sodium D line, 589 nm) and temperature, then calculate specific rotation to confirm optical purity and stereochemistry. |
| Content Assay | High-Performance Liquid Chromatography (HPLC) | Use reversed-phase HPLC (e.g., C18 column) with UV detection (e.g., 210–230 nm), employing external or internal standard methods for quantification of the main component. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separate the main peak from impurity peaks via gradient or isocratic elution, detect and quantify related substances to evaluate sample purity. |
| Water Content | Karl Fischer Titration | Quantitatively determine moisture content in the sample using Karl Fischer reagent, suitable for trace water analysis. |
| Residual Solvents | Gas Chromatography (GC) | Detect organic solvents (e.g., methanol, ethanol, dichloromethane) potentially remaining from manufacturing processes using headspace or solution injection. |
| Residue on Ignition | Residue on Ignition Test | Ignite the sample at high temperature until constant weight to determine non-volatile inorganic impurities, reflecting inorganic impurity levels. |
| Heavy Metals | Heavy Metal Testing (e.g., Sulfide Method or ICP-MS) | Detect heavy metal impurities such as lead and cadmium using colorimetric methods (e.g., Chinese Pharmacopoeia method) or inductively coupled plasma mass spectrometry (ICP-MS). |
| Elemental Impurities | ICP-MS or ICP-OES | Quantitatively detect catalyst residues (e.g., Pd, Pt, Ni) to comply with ICH Q3D guideline on elemental impurities. |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Use ¹H NMR and ¹³C NMR to confirm molecular structure, including backbone and substitution positions. |
| Structural Confirmation | Mass Spectrometry (MS) | Determine molecular ion peaks and fragment ions via LC-MS or EI-MS to verify molecular weight and structural information. |
| Polymorphic Analysis | X-Ray Powder Diffraction (XRPD) | Analyze crystalline structure characteristics of solid samples to identify different polymorphs or monitor polymorphic stability. |
| Particle Size Distribution | Laser Particle Size Analysis | Determine particle size distribution of active pharmaceutical ingredients, which affects dissolution rate and formulation performance. |
