Industrial Applications of BOC-LYS(BOC)-ONP
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Side-chain protecting reagent for lysine residues in peptide synthesis | Used in solid-phase peptide synthesis (SPPS) to selectively protect the ε-amino group of lysine and prevent side reactions; the Boc group is cleaved under acidic conditions (e.g., TFA), while ONP (p-nitrophenol) serves as an activated leaving group to facilitate subsequent coupling |
| Biochemistry | Modification intermediate for structural and functional studies of proteins/peptides | Used to prepare site-specifically modified peptide probes—such as fluorescent or biotinylated precursors—via efficient amine coupling using the ONP-activated ester |
| Organic Synthesis | Building block for unnatural amino acid derivatives and pharmaceutical molecules | Employed as a chiral synthon in total synthesis of complex molecules, e.g., for introducing side-chain functionality in anticancer peptide drugs (such as precursors to certain histone deacetylase inhibitors) |
Manufacturing Quality Control of BOC-LYS(BOC)-ONP
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by retention time and UV absorbance relative to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents based on retention time and flame ionization response. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| Optical Rotation | Polarimetry | Determines specific rotation using plane-polarized light to confirm chiral integrity and enantiomeric purity. |
| Heavy Metals | ICP-OES | Quantifies trace metal contaminants (e.g., Pb, Cd, Ni) by atomic emission after acid digestion. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content after high-temperature incineration and weighing of residual residue. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and purity. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against established reference standards under controlled lighting. |
| pH of Solution | pH Meter | Measures hydrogen ion activity in aqueous suspension or solution using calibrated glass electrode. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles by measuring angular variation in scattered laser light intensity. |
