| Pharmaceuticals | Synthesis of pharmaceutical intermediates | Organic synthesis process for preparing biologically active compounds |
| Chemical Research | Research chemical | Intermediate in organic synthesis for structural modification and functional studies |
Manufacturing Quality Control of 196404-55-4
| Detection Item | Common Detection Method | Method Overview |
|---|---|---|
| Chemical Structure Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Analyze hydrogen and carbon atom chemical shifts using 1H-NMR and 13C-NMR to confirm molecular framework and stereochemistry. |
| Purity Analysis | High-Performance Liquid Chromatography (HPLC) | Use a reverse-phase column with a UV detector (e.g., 220 nm or 254 nm) to quantitatively determine the main component and assess impurity content. |
| Enantiomeric Purity / Enantiomeric Excess | Chiral High-Performance Liquid Chromatography (Chiral HPLC) | Separate enantiomers using a chiral stationary phase column, determine the percentage of (4S,5R) configuration, and ensure stereochemical purity. |
| Moisture Content | Karl Fischer Titration | Precisely measure trace moisture in the sample using titration, controlling hygroscopicity's effect on stability. |
| Residual Solvents | Gas Chromatography (GC) | Analyze residual organic solvents (e.g., ethyl acetate, methanol, toluene) using headspace or direct injection with an FID detector. |
| Melting Point Determination | Capillary Melting Point Apparatus | Determine the temperature at which a substance transitions from solid to liquid, serving as a physical constant for identification and purity assessment. |
| Specific Rotation | Polarimeter | Determine specific rotation [α] at a specified wavelength (e.g., sodium D line, 589 nm) to verify consistency in the configuration of chiral centers. |
| Heavy Metal Residue | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Atomic Absorption Spectroscopy (AAS) | Detect residues of elements such as lead, arsenic, cadmium, and mercury, complying with ICH Q3D requirements. |
| Drying Loss | Oven Drying Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight is achieved, calculating the percentage loss of volatile substances. |
| Related Substances / Impurity Profile | HPLC-UV or LC-MS | Separate and identify process-related impurities and degradation products using gradient elution, combined with mass spectrometry for structural inference. |
