Manufacturing Quality Control of N-[(S)-(+)-1-(Ethoxycarbonyl)-3-phenylpropyl]-L-alanine
| Test Item | Common Analytical Method | Method Description |
|---|---|---|
| Chemical Structure Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Analyze hydrogen and carbon atom chemical shifts via ¹H-NMR and ¹³C-NMR to confirm molecular structure and stereochemistry. |
| Purity Analysis | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase chromatographic column and UV detector (e.g., 210–220 nm) to quantify the main component and detect related substance impurities. |
| Related Substances/Impurity Detection | HPLC (Gradient Elution) | Separate potential process impurities or degradation products using a gradient elution program, and assess impurity content based on relative retention time and peak area. |
| Enantiomeric Purity | Chiral High-Performance Liquid Chromatography (Chiral HPLC) | Use a chiral stationary phase column to separate and quantify diastereomers or enantiomer impurities to ensure optical purity. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Loss on Drying Method | Determine mass loss of the sample at a specified temperature (e.g., 105°C) under constant weight to evaluate moisture and volatile matter content. |
| Residual Solvents | Gas Chromatography (GC), Headspace Sampling | Quantify residual organic solvents (e.g., ethanol, ethyl acetate) according to ICH Q3C using a capillary column and FID detector. |
| Melting Point Determination | Capillary Melting Point Apparatus | Determine the melting point range as a physical constant for preliminary identification and purity assessment. |
| Specific Rotation | Polarimeter | Measure optical rotation at a specified wavelength (usually 589 nm, sodium D line) and concentration to verify the configuration and purity of chiral centers. |
| pH Value (in Solution) | pH Meter | Dissolve the sample into an aqueous solution at a certain concentration and measure pH to assess its acidity, basicity, and stability. |
| Heavy Metal Residues | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Atomic Absorption Spectroscopy (AAS) | Determine residues of lead, arsenic, cadmium, mercury, etc. after digestion according to pharmacopoeia methods to ensure compliance with safety limits. |
| Ignition Residue | Muffle Furnace Ashing Method | Weigh the residue after high-temperature calcination (e.g., 600–800°C) to assess inorganic salt or metal catalyst residues. |
