Manufacturing Quality Control of BOC-PHE-OSU
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Chiral Purity | Chiral HPLC | Separation of enantiomers on a chiral stationary phase; L-isomer content determined by relative peak area. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., ethyl acetate, methanol) using flame ionization detection with headspace sampling. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine reagent to determine trace water based on stoichiometric reaction with iodine and sulfur dioxide. |
| Heavy Metals | ICP-MS | Multi-element detection and quantification of toxic metals (e.g., Pb, Cd, Hg) after acid digestion using inductively coupled plasma mass spectrometry. |
| Residual Palladium | ICP-OES | Quantification of palladium catalyst residues after microwave-assisted digestion using inductively coupled plasma optical emission spectrometry. |
| Related Substances | HPLC-UV | Detection and quantification of structurally related impurities (e.g., Boc-L-phenylalanine, hydroxylamine derivatives) using gradient reversed-phase HPLC. |
| Optical Rotation | [alpha]D Measurement | Determination of specific rotation using a polarimeter at 20 degC with sodium D-line (589 nm) to confirm chiral integrity. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as the temperature range over which solid-to-liquid phase change occurs under controlled heating. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles or clumping under controlled lighting conditions. |
| pH of Solution | Potentiometric pH Measurement | Measurement of hydrogen ion activity in a standardized aqueous suspension using a calibrated glass electrode. |
| Residual Chloride | Ion Chromatography | Quantification of chloride ions after sample dissolution and filtration, using conductivity detection with anion-exchange column. |
