Manufacturing Quality Control of (1S,2R)-2-Amino-1,2-diphenylethanol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 210-230 nm, comparing peak area to calibrated standard. |
| Enantiomeric Excess (ee) | Chiral HPLC | Separates (1S,2R) and (1R,2S) enantiomers on a chiral stationary phase; ee calculated from peak area ratio. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine-sulfur dioxide-pyridine-methanol reagent system. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., ethanol, toluene) using gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-OES | Quantifies Pb, Cd, Hg, As, and other metals after acid digestion by measuring atomic emission intensities at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfate Impurity | Ion Chromatography | Separates and quantifies sulfate ions using anion-exchange column and suppressed conductivity detection. |
| Related Substances | HPLC-UV | Identifies and quantifies structurally related impurities (e.g., deaminated or oxidized analogs) using gradient HPLC-UV. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity via thermal behavior. |
| Optical Rotation | Polarimetry | Measures specific rotation at sodium D-line (589 nm) to confirm chiral integrity and concentration-dependent rotation. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a standardized aqueous suspension (e.g., 1% w/v) to assess acidic/basic impurities. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature ignition (700-800 C) followed by weighing of residual residue. |
