Industrial Applications of BOC-D-PHE-OSU
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Protected D-phenylalanine intermediate for chiral drug synthesis | Used for Nα-tert-butoxycarbonyl (BOC) protection and active esterification of D-phenylalanine residues in solid-phase peptide synthesis (SPPS), facilitating subsequent coupling to resin or amino acids |
| Peptide Chemistry | Construction of bioactive peptides containing D-phenylalanine | Undergoes amidation with amine components under basic conditions (e.g., DIPEA/DCM); the OSu (N-hydroxysuccinimide) group provides high reactivity and favorable leaving-group properties |
| Organic Synthesis | Chiral building block for asymmetric catalysis and structural modification | Serves as an optically pure D-configured substrate in fine synthetic steps such as enzymatic resolution, chiral ligand derivatization, or cyclization reactions |
Manufacturing Quality Control of BOC-D-PHE-OSU
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC with UV detection and relative response factors. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., DMF, THF, ethyl acetate) by headspace GC with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine-based redox reaction in anhydrous methanol medium. |
| Optical Rotation | [alpha]D Measurement | Measures specific optical rotation using a polarimeter at 20 C and sodium D-line (589 nm) to confirm chiral integrity. |
| Heavy Metals | ICP-MS | Quantifies trace metals (e.g., Pb, Cd, Hg, Ni) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Residual Palladium | ICP-OES | Determines palladium residue from catalytic steps by microwave-assisted digestion followed by ICP optical emission spectroscopy. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of solid sample against established reference standards under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary apparatus per USP <741>. |
| Loss on Drying | Gravimetric Analysis | Measures weight loss after drying under specified vacuum/temperature conditions to determine volatile content. |
| Microbial Limits | Membrane Filtration | Detects aerobic microorganisms by filtration, membrane transfer to culture media, and colony enumeration per USP <61>. |
