Manufacturing Quality Control of (1R,2R)-(+)-1,2-Diphenylethylenediamine
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample visually for color, physical state (e.g., white to off-white crystalline powder), and presence of foreign matter. |
| Melting Point | Capillary Melting Point Determination | Determine the melting point of the sample using a melting point apparatus to verify purity and crystalline form consistency. |
| Specific Rotation | Polarimetry | Determine the optical rotation of the sample solution at a specified wavelength (usually sodium D line, 589 nm) and temperature to confirm optical purity and configuration ((1R,2R) configuration should have a specific specific rotation value). |
| Identification | Infrared Spectroscopy (IR) | Compare characteristic absorption peaks (such as N–H, C–N, aromatic ring functional groups) with standard spectra to confirm the molecular structure. |
| Nuclear Magnetic Resonance Hydrogen Spectroscopy (¹H NMR) | Analyze hydrogen atom chemical shifts and coupling constants to confirm molecular structure and stereochemistry. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Quantify the main component content using reverse or normal phase chromatography columns with a UV detector (e.g., 254 nm) to assess purity. |
| Enantiomeric Excess (e.e.) | Chiral High-Performance Liquid Chromatography (Chiral HPLC) | Separate enantiomers using a chiral stationary phase column and calculate the enantiomeric purity of the (1R,2R) isomer (e.e. ≥ 99% is common). |
| Related Substances (Impurities) | HPLC | Detect and quantify possible organic impurities (such as monobenzyl derivatives, oxidation products, etc.) using gradient or isocratic elution programs. |
| Moisture | Karl Fischer Titration | Determine moisture content using coulometric or volumetric methods to control drying loss or residual solvent effects. |
| Residual Solvents | Gas Chromatography (GC) | Detect residual organic solvents (such as methanol, ethanol, dichloromethane, etc.) from synthesis or purification processes using headspace or direct injection. |
| Residue on Ignition / Ash Content | Gravimetric Method | Weigh the mass of inorganic residues after high-temperature incineration to assess the content of inorganic impurities. |
| pH Value (if prepared as a solution) | pH Meter Measurement | Dissolve the sample in water to a certain concentration and measure its pH value to reflect the presence of acidic or basic impurities. |
